Answer:
-1 = x
Step-by-step explanation:
Distribute 2 into x - 10 first to get to this equation which is -22 = 2x - 20. Add 20 on both sides to get -2 on the left side. Divide 2 on both sides to get your x-value which is -1.
Marta put $4.89 in her coin bank. Each day she added 1 quarter, 1 nickel, and 6 pennies. How much does she add each day? How much money was in her coin bank after 6 days?
Step-by-step explanation:
Marta put $4.89 in her coin bank.
Each day she added 1 quarter, 1 nickel, and 6 pennies.
We know that,
1 quarter = 25 cents
1 nickel = 5 cents
1 penny = 1 cent
⇒ 6 pennies = 6 cent
Total amount added in 6 days,
= 25 cents + 5 cents + 6 cent
= 36 cents
We know that,
1$ = 100 cents
36 cents = $0.36
Total money in her bank,
= $4.89 + $0.36
= $5.25
Hence, this is the required solution.

A pair of pants that Jessica wants are usually $39. If the store is having a 33% off sale, how much will the pants cost
Answer: $12.87
Step-by-step explanation:
You need to set up your equation. We are trying to find x.
Step 1: [tex]\frac{x}{39} = \frac{33}{100}[/tex]
Step 2: Multiply across: 39 x 33 divided by 100.
39 x 33 = 1287
1287 divided by 100 = $12.87

A recipe code lasagna calls for 3 pounds of tomatoes to serve 5 people. A caterer wants to make enough lasagna to serve 110 people. How many pounds of tomatoes does he neeed
Answer:
66 pounds of tomatoes
Step-by-step explanation:
A recipe code lasagna calls for 3 pounds of tomatoes to serve 5 people. A caterer wants to make enough lasagna to serve 110 people. How many pounds of tomatoes does he neeed
From the above question:
5 people = 3 pounds of tomatoes
110 people = x pounds of tomatoes
Cross Multiply
5 people × x pounds = 110 people × 3 pounds
x pounds = 110 people × 3 pounds/5 people
x pounds = 66 pounds of tomatoes
A seed company planted a floral mosaic of a national flag. The perimeter of the flag is 2,260 ft Determine the flag's width and length if the length is 290 ft greater than the width.
Answer:
length= 710 width= 420
Step-by-step explanation:
As we consider a rectangle we can replace "length" with l and "width" with w so that the perimeter will be:
2l+2w= 2260
With the length as:
l= w+290
The length, substituted into the perimeter is:
2(w+290)+2w=2260
Distribute:
4w+580=2260
Subtract:
4w=1680
Divide:
w=420
To find the length, take the width and add 290:
420+290=710
l=710

Angle EFG has a measure of 133º. Triangle EFG is rotated 180° counterclockwise about point F to create triangle E'F'G'.
what is the measure of angle E’F’G
Answer:[tex]313^{\circ}[/tex]
Step-by-step explanation:
Given
[tex]\angle {EFG}=133^{\circ }[/tex]
When rotated 180 degree clockwise gives E'F'G' which measures
[tex]\angle E'F'G'=180^{\circ}+133^{\circ}=313^{\circ}[/tex]
This can be explained by the below-given digram
Rotation is a rigid transformation.
The measure of angle E'F'G' is 133 degrees
Because rotation is a rigid transformation, it does not change the side lengths and the angle measures.
This means that the measure of angle EFG will remain unchanged after rotation.
i.e.
[tex]\mathbf{\angle E'F'G' = \angle EFG}[/tex]
Hence, the measure of angle E'F'G' is 133 degrees

The cost of a t-shirt was $30. Now the t-shirt costs $37.50. What is the percent of change? Do the work on your own paper and write your answer as a number.
Answer:
25%
Step-by-step explanation:
Given that,
Initial cost of a t-shirt = $30
Final cost of a t-shirt = $37.50
We need to find percent of change. The percentage change in any value is given by :
[tex]\%=\dfrac{\text{final value-initial value}}{\text{initial value}}\times 100\\\\=\dfrac{37.5-30}{30}\times 100\\\\=25\%[/tex]
Hence, the percentage error is 25%.

Answer:
[tex]2abcosC = 37[/tex]
Step-by-step explanation:
Given
[tex]a^2 + b^2 - 2abcosC = c^2[/tex]
Required
[tex]2abcosC[/tex]
[tex]a^2 + b^2 - 2abcosC = c^2[/tex]
Add [tex]2abcosC[/tex] to both sides
[tex]a^2 + b^2 - 2abcosC+2abcosC = c^2+2abcosC[/tex]
[tex]a^2 + b^2 = c^2+2abcosC[/tex]
Subtract [tex]c^2[/tex] from both sides
[tex]a^2 + b^2 -c^2= c^2 -c^2+2abcosC[/tex]
[tex]a^2 + b^2 -c^2= 2abcosC[/tex]
From the attachment:
[tex]a = 4[/tex] [tex]b = 5[/tex] and [tex]c = 2[/tex]
So, we have:
[tex]4^2 + 5^2 -2^2= 2abcosC[/tex]
[tex]16 + 25 -4= 2abcosC[/tex]
[tex]37= 2abcosC[/tex]

The formula for s is The perimeter of a regular octagon is p and the length of a side is s. s = p ÷ 8 Find the length of a side when the perimeter is 72 cm. cm Write down a formula for p in terms of s. p = Write down a formula for the perimeter of this regular shape. p = Find p when s is 9 cm. cm
Answer:
s = 9 cm
p = 8s
p = 72 cm
Step-by-step explanation:
s = p ÷ 8
Where,
s = length of a side
p = perimeter of a regular octagon
find s when p = 72 cm
s = p ÷ 8
= 72 cm ÷ 8
= 9 cm
s = 9 cm
Formula for p in terms of a
s = p ÷ 8
Equivalent to
s = p/8
Cross product
s * 8 = p
p = 8s
Find p when s = 9 cm
p = 8s
p = 8 * 9 cm
= 72 cm
p = 72 cm
