Step-by-step explanation:
lol ok got it bro
1.89 + 3.72 = 5.61
10.75 - 5.61= 5.14
5.14 x 100= 514
0.64 x 100= 64
(You can skip out the multiplying by 100 but doing this step makes it easier to do without a calculator)
514/64= 8.3
Round the number down to 8 and this is your answer.
Answer:
Step-by-step explanation:
we are given that 1 angle equals 27 and the other two are equal.
180-27=153. and the other two are equal so they each equal 76.5 (153 divided by 2) now since one of the angles is supplementary with angle x, they together must equal 180 so: 180-76.5=x, x=103.5
Answer:
15
Step-by-step explanation:
5a - 10b = 45
5a - (10×3) = 45
5a - 30 = 45
5a = 45 + 30
5a = 75
a = 15
The 9 is higher than 5, so the 3 will round up to 4
