Answer:
28 small
9 large
Step-by-step explanation:
4200 ÷ 150 = 28 small
4200 ÷ 450 =9 large
139b + 1.29b = 50.73
2.49m + 2.69m = 51.63
Answer:
1. 128
2. 52
3. 47
4. 133
5. 81
Step-by-step explanation:
1. <1 and <52 are same side interior angles, therefore supplementary. So they should add up to equal 180, this means that <1 is 180 - 52. Solve to get <1 is 128
2. <2 is an alternate interior angle to <52, this means that they are congruent. Since they are congruent, they have the same value of 52.
3. <3 is an alternate interior angle to <47, so they are congruent, this means that they both have a value of 47
4. <4 is supplementary to <3 so you can say that <4 is equal to 180 - 47. Solve this to get <4 is 133
5. <5, <52, and <47 are supplementary when you combine all three. So you can create an equation that says <5 is equal to 180 - 52 + 47. This gives you that angle 5 is 81.
Answer: C. (10, -10)
Step-by-step explanation:
Given
1) 2x-3y=50
2) 7x+8y=-10
Multiply both sides of 1) equation by 3.5
1) 3.5(2x-3y)=3.5×50
7x-10.5y=175
2) 7x+8y=-10
Subtract 2) equation from the 1)
(7x-10.5y)-(7x+8y)=175-(-10)
-18.5y=185
y=-10
x=10
(10, -10)
