Example: 2x + 6 < -8
There's 2 steps to solve this one.
2x + 6 < -8
Subtract 6 from both sides
2x < -14
Divide both sides by 2
x< -7
Let's call the missing angles Q, R, and S. We know that Q = 2R and S = R - 8 and we also know that Q + R + S = 180. So that really just means that 180 = 4R - 8 Add 8 on both sides of the equal sign
188 = 4R So we divide on both sides of the equal sign by 4
47 = R And that means that Q = 2 * 47 So Q = 94 and S = 47 - 8 So S = 39
39 + 94 + 47 = 180
The missing angles are 39 degrees 94 degrees and 47 degrees.
Answer:
the Answer is 150x + 12100 ≤ 26500
Step-by-step explanation:
The max weight is 26500 so the weight would have to be the same or less than 26500 (≤)
There is already 12100 killograms on the sipping containter so that is why you have + 12100
and you have 150x because x is the number of 150-kilogram crates
and for as many crates you have to multiply by the weight.
Answer:
A
Step-by-step explanation:
As there is 5 more girls than boys and b is the number of boys, the expression b + 5 represents the number of girls.
total there are 27 childrens
b + (b+5) = 27
b + b + 5 = 27
2b = 27 -5
b =22 / 2
b =11
so the number of boys there are 11 and girls are 11 + 5 = 16
and total is 16 + 11 = 27
