Kam is trying to find the solution to the system below. Her steps are below as well.
What did kam do wrong?
Answer:
Step 4
Step-by-step explanation:
In step 4, instead of adding 22 to both sides of the equation to combine like terms, Kam got rid of it completely. Starting from step 3, here is the correct way of solving it:
[tex]7x-22=18[/tex]
Add 22 to both sides
[tex]7x-22+22=18+22\\7x=40[/tex]
Divide both sides by 7 to isolate x
[tex]\frac{7x}{7}=\frac{40}{7} \\x=\frac{40}{7}[/tex]
I hope this helps!
Answer:
In step 4, she forgot to add 22 to 18
Step-by-step explanation:
In step 4, she forgot to add 22 to 18
It should've been:
7x = 40
x = 40/7
3 (40/7) + 2y = 18
120/7 + 2y = 18
2y = 18 - 120/7
2y = 6/7
y = 3/7
What is the product of -4 and 2 3/5
Answer:
6 3/
5
= 6.6
Step-by-step explanation:
Conversion a mixed number 2 3/
5
to a improper fraction: 2 3/5 = 2 3/
5
= 2 · 5 + 3/
5
= 10 + 3/
5
= 13/
5
To find new numerator:
a) Multiply the whole number 2 by the denominator 5. Whole number 2 equally 2 * 5/
5
= 10/
5
b) Add the answer from previous step 10 to the numerator 3. New numerator is 10 + 3 = 13
c) Write a previous answer (new numerator 13) over the denominator 5.
Two and three fifths is thirteen fifths
Add: 4 + 13/
5
= 4/
1
+ 13/
5
= 4 · 5/
1 · 5
+ 13/
5
= 20/
5
+ 13/
5
= 20 + 13/
5
= 33/
5
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(1, 5) = 5. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 1 × 5 = 5. In the next intermediate step the fraction result cannot be further simplified by canceling.
In words - four plus thirteen fifths = thirty-three fifths.

Which figures appear to be congruent?
An image of 5 triangles on a 14 by 12 grid is shown.Triangle 1 has a base that is 4 units long. The upper vertex is 4 units above the midpoint of the base. To the right, triangle 2 has a horizontal leg that is 3.5 units long and a vertical leg that is 4 units long. A small square is positioned in the triangle at the lower left vertex. Below triangle 1, triangle 3 has a horizontal leg that is 3.5 units long and a vertical leg that is 4 units long. A small square is positioned inside this triangle at the upper right vertex. Triangle 4 is toward the center of the grid. It has a horizontal leg that is 1 unit long and a vertical leg that is 4 units long. A small square is positioned inside this triangle at the upper right vertex. Triangle 5 is to the lower right. It has a horizontal leg that is 6 units long and a vertical leg that is 4 units long. A small square is positioned inside this triangle at the lower left vertex.

Amber is on a family cell phone plan with the other 2 members of her family. The family gets 744 shared cell phone minutes a month, and each family member is limited to his or her equal share of the minutes. The only free calls are calls between family members. How many minutes per day can Amber talk on her cell phone with her friends during a 31-day month, without going over her share of the minutes?
Answer:
8 Minutes
Step-by-step explanation:
When dividing 744 by 3 family members you will get 248 minutes, but then dividing by 31 to tell the number for how long they can all be on per day you will get 8. 744 ÷ 3 ÷ 31 = 8.
