Answer:
x=35
Step-by-step explanation:
62+2x+(x+13)=180
62+2x+x+13=180
3x+75=180
3x=180-75
3x=105
x=35
It would be -1.2

Answer:
Size of groups known: First and last questions (The rice and cups ones)
Number of groups known: Second and third questions (Cars and hats)
Step-by-step explanation:
In the first problem, you know that one sack is one group, and it tells you that each sack weighs 3 kg. Therefore, you know the size of the group (or a sack).
In the last one, you know that a table is one group and each table fits 4 cups. So, you know that the size of the group is 4 cups.
In the second and third questions, you know that each group is a row (cars) or "equal group" (hat) and that there are 4 of each. So, you know that there are 4 of each group, meaning you know the "number of groups"
Answer:170
Step-by-step explanation:
Multiply 210 by 0.70 because that's equal to 70%. This will give you the answer.
Answer:
Ok if you look at the figure, it is a vertical angle. This means that the angle opposite to each other is congruent.
m<1 is congruent to m<3
m<2 is congruent to m<4
m<3 is 60⁰ and is congruent to m<1. This means that m<1 is 60⁰. m<4 is 30⁰ and is congruent to m<2. This means that m<2 is 30⁰.
m<1 = 60⁰
m<2 = 30⁰
m<3 = 60⁰
m<4 = 30⁰
Hope this helps, thank you :) !!
