Triangles ABC and DEF are similar.
Answer: Segment DF is equal to 2.68. Segment EF is equal to 2.01
Step-by-step explanation: If you divide the smaller triangle by the bigger triangle, you will get .67, which can then be multiplied by the segments AC (DF) and BC (EF). Segment AC: 4*0.67=2.68 (Equal to segment DF). Segment BC: 3*0.67=2.01 (Equal to Segment EF).

Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define systems
7x + 3y = 12
7x - 3y = 30
Step 2: Solve for x
Eliminate y: 14x = 42Isolate x: x = 3Step 3: Solve for y
Substitute in x: 7(3) + 3y = 12Multiply: 21 + 3y = 12Isolate y term: 3y = -9Isolate y: y = -3And we have our final answer!

Helena, Violet, and Kaneesha are on a baseball team. They each bought a baseball and x pairs of sweat socks. Write an expression to show the teams purchase. !(x*y)+(x*y)!
Baseball - $5
Sweat Socks - $7
Soccer Ball - $21
Answer:
Step-by-step explanation:
Helena Violet Kaneesha
1b 1b 1b
x pairs x pairs x pairs
Helena 1b + x pairs of socks
Helena = 1 b(baseball) + $7X ( X is the number of pairs of socks)
Helena ----- $5 + 7X
Since all 3 bought the same thing, multiply the above by 3
answer = 3(5 +7x)
or Distribute
Answer = (3*5) + (3*7x)
I only know + I don’t know - pls helpp!!
Answer:
x=31
Step-by-step explanation:
Since these angles are on a straight line, they are supplementary (combine to make 180 degrees. Therefore we can set up an equation to find x.
(5x-16)+(x+10)=180
Drop the parentheses.
5x-16+x+10=180
Combine like terms.
6x-6=180
Add 6 to both sides.
6x=186
Divide both sides by 6.
x=31

The surf instructor has an initial fee of $12 and charges $8 per hour for lessons, which is represented by the equation y = 8x + 12, where x is the number of hours and y is the total cost. The instructor gives 32 hours of lessons a month to Sandra and 24 hours of lessons a month to Bela. What is the total amount the instructor makes in a month? Sandra: y = 8 (32) + 12. y = 256 + 12. y = 268. The instructor receives 268 dollars a month from Sandra. The instructor makes $ a month.

For Emily’s birthday, her father treated her and five friends to a dinner at a restaurant at the mall. Emily and her friends ordered three pizza dinners at $6.25 each and three chicken baskets at $7.50 each. All six people ordered soft drinks costing $1.25 each. The sales tax on the meal was 4.5%, and the tip was 15%. What was the total cost of the meal, including the sales tax and the tip?
Answer:
$58.58
Step-by-step explanation:
the meal was $48.75
the tax was 4.5%
Multiply 48.75 by 4.5 as a decimal to do this divide 4.5 by 100 = 0.045
48.75 x 0.045 = 2.19375 round to the nearest hundreth = 2.19
48.75 + 2.19 = 50.94
tip on tax = 58.58

Answer:
x = 33
Step-by-step explanation:
This picture shows a supplementary angle which means:
angle 1 + angle 2 = 180°
In order to solve for x, you need to add both the angles
(2x + 1) + (4x - 19) = 180° start by simplifying this equation by adding like terms
6x - 18 = 180° you can solve this like a regular inequality now, add 18 to 180°
6x = 198 now divide 6 by 162
x = 33

Which of the following describes a situation for the inequality: 3w + 9 ≤ 21
A. A girl get $3 for every box of cookies sold plus 9 dollars for trying. She makes either $21 total or just below that amount.
B. A girl get $3 for every box of cookies sold plus nine dollars for trying. She makes either $21 total or more than that amount.
C. Girl scout cookies are good, just pay the girl! (this is not the correct answer.)
D. A girl get $9 for every box of cookies sold plus 3 dollars for trying. She makes either $21 total or just below that amount.
Answer:
B

Answer: The answer would be A. A girl gets $3 for every box of cookies sold plus 9 dollars for trying. She makes either $21 total or just below that amount.
Step-by-step explanation:
w is the box and when a number is beside a letter it is multiplication and then 9 dollars for trying. the < with the underline means that it is the same amount or less.
