Answer:
-220
Step-by-step explanation:
-5 x 1 x 11 x 4
times -5 and 1 = -5
-5 times 11 is -55
-55 times 4 is -220
Section 1:
using this format we can determine what the answer is:
42 105
—— • ——-
100 x
(the spacing may be off but imagine two separate fractions)
first multiply 100 by 105 to get 10,500
then divide by 42 to get 250
this means that sasha’s book has 250 pages
section b:
using the same formula we can solve this problem:
first we need to multiply 250 by 2 to get the total cost of both tickets
175 x
—— • ——
100 500
(again spacing may be off but think of two separate fractions)
then multiply 500 by 175 to get 87,500
then divide by 100 to get 875
to find the profit subtract 875-500
this means he will make $375 profit
conclusion:
sasha’s book has 250 pages
trevor will make $375 profit
this is the method my teacher taught me last year so it should be right, hope this helps and please mark brainliest!!
A straight angle measures 180º.
A triangle's interior angles also measure 180º.
The angle measuring 130º is complementary to the corresponding interior angle, so that interior angle plus 130 has to equal exactly 180º.
180 - 130 = 50º
45 + 50 = 95º, so subtract that from 180 to find the measure of the last interior angle of the triangle.
180 - 95 = 85º
That angle of 85º is complementary to the other outside angle, n, and to find that subtract 85 from 180.
180 - 85 = 95º
n = 95
Hope this helps!
Answer:
B) 4y - 2 - 3y = 6
Step-by-step explanation:
x = 4y - 2 Substitute this into the second solution
x - 3y = 6
4y - 2 - 3y = 6
