Answer: 38 for x, 61 for bottom left angle, 81 for top angle.
Step-by-step explanation:
Since all angles must add up to 180 degrees, that means that (2x+5) + (2x-15)+x must equal to 180. If you add and simplify correctly, x equals 38. The other angles can be figured out once you found x.
2 Cassie has a family photograph that measures 5-inches wide and 7-inches long. She wants to enlarge the photograph and hang it on the wall. If the length of the enlarged photograph is 87.5 inches, what is the width of the enlarged photograph?
Answer:
62.5 inches
Step-by-step explanation:
We would solve this using ratio
Width : Length = Width/Length
For the Original photo
5 inches : 7 inches = 5/7
For the enlarged phots
x : 87.5 inches = x/87.5
Equating both ratios together, we have:
5/7 = x /87.5
Cross Multiply
7x = 5 × 87.5
7x = 437.5
x = 437.5/7
x = 62.5 inches
Hence, the width of the enlarged photo is 62.5 inches

In one year, a school uses 13,270 pieces of white paper, 6,570 fewer pieces of blue paper than white paper, and 2,600 fewer pieces of yellow paper than blue paper. How many pieces of paper does the school use in all?
Answer:
24,070 the school uses in all
Step-by-step explanation:
You subtract 13,270 by 6,570 and you get 6,700 pieces of blue paper. Then, you subtract 6,700 by 2,600 and you get 4,100 pieces of yellow paper. Finally, you add the total of pieces of white, blue, and yellow paper and you get 24,070 for the total.
Joaquin is ordering 5 identical sandwiches and a bag of chips. The bag of chips cost $1.25 and the entire order costs $38.75. Write an equation you can use to find the price of the sandwhich. Let’s represent the price of the sandwhich.
Answer:
A sandwich costs $7.5
Step-by-step explanation:
Given
Represent chips with c and sandwiches with c
[tex]c = \$1.25[/tex]
[tex]Total = \$38.75[/tex]
From the question, we understand that 5 sandwiches were ordered.
Hence, the question of the system is:
[tex]5s + c = Total[/tex]
Substitute values for Total and c
[tex]5s + 1.25 = 38.75[/tex]
Collect Like Terms
[tex]5s = 38.75 - 1.25[/tex]
[tex]5s = 37.5[/tex]
Divide both sides by 5
[tex]s = \frac{37.5}{5}[/tex]
[tex]s = 7.5[/tex]

= 5/(8 + 12 + 5) = 5/25 = 1/5
= 1/5 *100 = 20%
Answer:
5%
Step-by-step explanation:
Total outcome is 100
Favorable outcome is 5
The probability that a customer ordered a large cold drink is
[tex]\frac{5}{100}[/tex] = [tex]\frac{1}{20}[/tex] = 5%

Use this rule to fill in the table.
Rule: Add 3 to the input to get the output.
Add 3
?
Input
Output
1
0
6
11
Answer:
Input --- Output
1 ------------ 4
6 ------------9
8--------------11
Step-by-step explanation:
Given
Rule:
Output = Input + 3
Required
Complete the table
Represent the input with x and the output, y
So, the rule becomes
[tex]y = x + 3[/tex]
When Input = 1
[tex]x = 1[/tex]
[tex]y = x + 3[/tex]
[tex]y = 1 + 3[/tex]
[tex]y = 4[/tex]
This means:
Output = 4
When Input = 6
[tex]x = 6[/tex]
[tex]y = x + 3[/tex]
[tex]y = 6+3[/tex]
[tex]y = 9[/tex]
This means:
Output = 6
When output = 11
[tex]y = 11[/tex]
[tex]y = x + 3[/tex]
[tex]11 = x + 3[/tex]
[tex]x = 11 -3[/tex]
[tex]x = 8[/tex]
This means
Input = 8
So, the complete table is:
Input --- Output
1 ------------ 4
6 ------------9
8--------------11

The first five terms of a sequence are 7, 10, 13, 16, and 19.
Which of the following functions define this sequence for all integers n ≥ 1?
Answer:
Option B is correct
For , the function for the given sequence is defined as;
Step-by-step explanation:
An arithmetic sequence is a sequence in which the difference between each consecutive term is constant.
An explicit formula for this arithmetic sequence given by;
where a represents first term
Since, the given sequences; 7 , 10 , 13 , 16 and 19
⇒ common difference(d) = 3 and a = 7
Since.
10 -7 = 3
13- 10 = 3 ....
The function which defined this sequence is;
using distributive property:
therefore, the function for the given sequence for all integers is;
