Answer:
2x+90=130
Step-by-step explanation:
perimeter formula: l+l+w+w=p or 2l+2w=130
l=x
w=45
plug into formula
2x+2(45)=130
2x+90=130
Solve for x show work for brainly
Answer: x = 18
Step-by-step explanation:
90 + 64 + ( x + 8 ) +180
x + 8 = 26 x = 18
Emilio has a gift card with $250 on it. He uses the gift card to buy 5 DVD's.
Adam has a gift card with $150 and uses it to purchase 4 DVD's.
If they both now have the same amount left on their gift cards, how much did each DVD cost?
Answer: Each DVD cost $100
Step-by-step explanation:
So it's a system of equations, where x = DVD price and y = remainder...
250 - 5x = y
150 - 4x = y
Now let's find x by making the y's cancel out.
In order to do this, multiply one equation by -1!
-250 + 5x = -y
150 - 4x = y
Which equals to...
-100 + x = 0
Add 100 to both sides...
x = 100
MEANING that each DVD cost $100. Quite pricey if you ask me!
DP 2.6 Similar Polygons
Triangle DEF is a dilation of triangle ABC with scale factor 2. In triangle ABC, the largest angle measures 82o. What is the largest angle measure in triangle DEF?
41∘
82∘
180∘
164∘
What characteristics are needed to determine that two polygons are similar?
The quadrilateral PQRS in the diagram is a parallelogram. Which of the following statements would be true if P′Q′R′S′ is the image of PQRS after applying a dilation centered at a point O with scale factor 3?
P′Q′=PQ
P′Q′=3PQ
PQ=3P′Q′
Cannot be determined from the information given
A. Because changing the size of a polygon doesn't change its angles, it would stay at 82°.
B. The characteristics needed to prove they are similar are just their angles.
C. The scale factor is 3, so P'Q'=3PQ.

Answer: D. 140
Step-by-step explanation:
Goal: Find x and solve the equation
1) Since they are parallel angles, you can move QXY up to SQR.
Note: I don't really know how to explain this... Hope this is enough.
2) Set up the equation and solve
4x+40+2x-10 = 180
6x+30=180
6x = 150
x = 25
3) Solve the PQS equation
4x+40
4(25)+40 (Substitute x here.)
100+40

2p = 18; p = $9
12 + p = 30; p = $18
18 = p + 12; p = $6
Answer: $6
Step-by-step explanation: 12+6
Answer:
Step-by-step explanation:

please help asap i need help
Answer:
B
Step-by-step explanation:
If we are working in base five, then in the 1203, there would be 3 in the ones place. 3
In the 5 place, there is 0.
In the 25's place, there is a 2, which means 2*25=50
In the 125's place, there is a 1, 1*125=125.
125+50+3=178
Answer:
B. 178
Step-by-step explanation:
1203 to base 5 equals:
[tex](1 \times {5}^{3} ) + (2 \times {5}^{2} ) + (3 \times 1)[/tex]
[tex]125 + 50 + 3 = 178[/tex]

Step-by-step explanation:
Carl’s monthly income is $4,000. The circle graph below shows Carl’s monthly budget.
Part A: How much money did Carl budget for car payment each month?
Part B: How much money did Carl budget for food each month?
Answer:
$600 for car payment
$200 for food
Step-by-step explanation:
all you need to do is change the percent to a decimal 15% = 0.15 5% = 0.05
then multiply that decimal with the amount of money in this case, $4,000 so...
car payment = 0.15 × 4000 = 600
food = 0.05 × 4,000 = 200
Answer:
Part A: Carl spent $600 for car payment each month.
Part B: Carl spent $200 for food payment each month.
Step-by-step explanation:
Part A: 15% of $4000 which is 15% x 4000 = $600
Part B: Step 1 50+20+15+10=95
Step 2 95-100 is 5 which is 5%
Step 3 5% of $4000 which is 5% x 4000 = $200
