Answer:
w = (-6)/7
Step-by-step explanation:
Solve for w:
-w/2 - 3/5 = w/5
Hint: | Put the fractions in -w/2 - 3/5 over a common denominator.
Put each term in -w/2 - 3/5 over the common denominator 10: -w/2 - 3/5 = (-5 w)/10 - 6/10:
(-5 w)/10 - 6/10 = w/5
Hint: | Combine (-5 w)/10 - 6/10 into a single fraction.
(-5 w)/10 - 6/10 = (-5 w - 6)/10:
(-5 w - 6)/10 = w/5
Hint: | Make (-5 w - 6)/10 = w/5 simpler by multiplying both sides by a constant.
Multiply both sides by 10:
(10 (-5 w - 6))/10 = 2 w
Hint: | Cancel common terms in the numerator and denominator of (10 (-5 w - 6))/10.
(10 (-5 w - 6))/10 = 10/10×(-5 w - 6) = -5 w - 6:
-5 w - 6 = (10 w)/5
Hint: | In (10 w)/5, divide 10 in the numerator by 5 in the denominator.
10/5 = (5×2)/5 = 2:
-5 w - 6 = 2 w
Hint: | Move terms with w to the left hand side.
Subtract 2 w from both sides:
(-5 w - 2 w) - 6 = 2 w - 2 w
Hint: | Combine like terms in -5 w - 2 w.
-5 w - 2 w = -7 w:
-7 w - 6 = 2 w - 2 w
Hint: | Look for the difference of two identical terms.
2 w - 2 w = 0:
-7 w - 6 = 0
Hint: | Isolate terms with w to the left hand side.
Add 6 to both sides:
(6 - 6) - 7 w = 6
Hint: | Look for the difference of two identical terms.
6 - 6 = 0:
-7 w = 6
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides of -7 w = 6 by -7:
(-7 w)/(-7) = 6/(-7)
Hint: | Any nonzero number divided by itself is one.
(-7)/(-7) = 1:
w = 6/(-7)
Hint: | Simplify the sign of 6/(-7).
Multiply numerator and denominator of 6/(-7) by -1:
Answer: w = (-6)/7
Answer:
-5/10w - 3/5 = 2/10w
- 3/5 = 7/10w
-30 = 35w
-30/35 = w
-6/7 = w

find the area of the figure
Answer:
[See Below]
Step-by-step explanation:
✦ In this figure there are two shapes; A triangle and a square. So you'll need to know the area formula for both:
✧ Square ∼ s² (Side Squared)
✧ Triangle ∼ ½ × b × h
✦ So now just solve for each area:
✧ Square ∼ 15² = 225
✧ Triangle ∼ ½ × 15 × 3 = 22.5
✦ Now add each area together to get the total area:
✧ 225 + 22.5 = 247.5

12x-3x=-15+12
9x =-3
9÷-3
x=-3
Answer:
X= - 1/3Step-by-step explanation:
3(4x+5) = 3x+1212x + 15 = 3x + 1212x - 3x = 12 - 159x = - 3X = -3/9 = - 1/3Hope this helps..Please answer this . It’s of class 8 Thank you
Answer:
= (3/5)-³
= (5/3)³

An electric pole, 14 metres high, casts a shadow of 10 metres. Find the height of a tree that casts
a shadow of 15 metres under similar conditions.
As shadow is directly propotional to height, we can say that,
Height/Shadow =k, where k is a constant.
So, in case of electric pole,
1410=k→(1)
In case of tree,
HT15=k→(2), where HT is height of tree
So, from (1) and (2),
1410=HT15
HT=14∗1510=21m
So, height of tree is 21 meters.
hope it helps thank youuuu

7. Bruno noticed today's gasoline price at the local convenience store was advertised as $3.40 per gallon. This price is 15% above last year's price. Calculate last year's price. $ 3.55 O $ 3.25 O $ 2.96 O $ 2.40
Answer:
I'm pretty sure it $2.96
Answer:
option c) $ 2.96
Step-by-step explanation:
15% = 15 /100 = 0.15
Let last year's price = $ x
x + 15% of x = $ 3.40
x + 0.15*x = 3.40
x + 0.15x = 3.40 {Add like terms}
1.15x = 3.40 {Divide both sides by 1.15}
1.15x/1.15=3.40/1.15
x = 2.956
Last year's price = $ 2.96

A box measuring 11 inches by 10 inches by 7 inches is filled with solid wooden cubical blocks, each measuring 3 inches per side. How many wooden blocks can fit into the box
Answer:
28
Step-by-step explanation:
[tex]number \: of \: wooden \: blocks \\ = \frac{volume \: of \: box}{volume \: of \: one \: wooden \: block} \\ = \frac{11 \times 10 \times 7}{3 \times 3 \times 3} \\ = \frac{770}{27} \\ = 28.51 \\ [/tex]
Thus, there would be 28 full wooden blocks in the box.
Answer: 28 wooden blocks
Step-by-step explanation: First you must find the volume of the box with the formula: L × W × H so, 10 × 11 × 7 = 770 inches³. Second you must find the volume of the wooden blocks with the formula: x³ ( 'x' is the value of the side of the cube ) so, 3 × 3 × 3 = 27 inches³. Now you can divide the volume of the box by the volume of the wooden block = 770 ÷ 27 = 28.518...*

Answer: OPTION 3. -7
Step-by-step explanation:
Given
-52=-4x-5(-2x+2)
Distributive property (REMEMBER you need to change signs)
-52=-4x-5×(-2x)-5×2
-52=-4x+10x-10
Combine like terms (-4x and 10x)
-52=6x-10
Add 10 on both sides
-52+10=6x-10+10
-42=6x
Divide 6 on both sides
-42/6=6/6x
x=-7
Hope this helps!! :)
Please let me know if you have any question
x = -7
[tex]-52=-4x-5(-2x+2)\\-52=-4x+10x-10\\-52=6x-10\\-42=6x\\-7=x[/tex]
to make sure, plug x in the equation:
[tex]-52=-4(-7)-5(-2(-7)+2)\\-52=28-5(14+2)\\-52=28-70-10\\-52=28-80\\-52=-52[/tex]

Answer:
Option (B)
Step-by-step explanation:
[tex]\begin{bmatrix}4 & 0\\ -1 & 2\\ -3 & -1\end{bmatrix}\times\begin{bmatrix}0 & 1 \\ -3 & 1\end{bmatrix}[/tex]
In the multiplication of two matrices we multiply the column of 1st matrix with the row of the 2nd matrix and add them.
= [tex]\begin{bmatrix}(4\times 0)+0(-3) &(4)1+0(1)\\ (-1)0+2(-3) &(-1)1+2(1)\\ (-3)0+(-1)(-3) &(-3)1+(-1)1 \end{bmatrix}[/tex]
= [tex]\begin{bmatrix}0 &4\\ -6 &1\\ 3 &-4 \end{bmatrix}[/tex]
Therefore, Option (B) will be the answer.
A jacket that normally sells for $45 is on sale with 20% off. What is the sale price? in dollars
Answer:
Step-by-step explanation:
The sales price would be $36.00
How I got this answer:
Discount: (45 x 20)/100 = $9.00 the nine dollars is your discount.
Final pricing:
45 - 9.00 = $36.00 when you subtract the cost with the discount you should get thirty-six dollars.
To make a salad dressing, a chef uses a ratio of 2 ounces of oil to 6 ounces of vinegar. The chef needs 24 ounces of dressing. How much oil is needed? 2 ounces 4 ounces 6 ounces 8 ounces 12 ounces also 8 ounces isn't right and when you find the answer can you show me how you worked it out?
Answer:
6 ounces of oil
Step-by-step explanation:
Well the first salad dressing is probably 8 ounces because 2+6 = 8
Then we must find out how large this recipe compares to the original
24/8 = 3
So we need all the ingredients to be tripled to keep the same ratio of 2:6
The new dressing has 2*3 ounces of oil and 6*3 ounces of vinegar
which equals 6 ounces of oil and 18 ounces of vinegar.

What value of x is in the solution set of 2(3x – 1) ≥ 4x – 6?
–10
–5
–3
–1
Answer: -1
Step-by-step explanation:
Given by your question
2(3x-1)≥4x-6
Distributive property to take off the parentheses
2×3x-2×1≥4x-6
6x-2≥4x-6
Subtract 4x on both sides (Subtractive property of equality)
6x-2-4x≥4x-6-4x
2x-2≥-6
Add 2 on both sides (Addition property of equality)
2x-2+2≥-6+2
2x≥-4
Divide 2 on both sides (Division property of equality)
2/2 x≥-4/2
x≥-2
