Yes, in my opinion I think a bar model would be a good model for converting miles to feet. It is simple and easy to understand
Step-by-step explanation:
2x + 1 + x - 13 = 180° because these angles are supplementary
3x - 12 = 180°
3x = 180 + 12
3x = 192 divide both sides by 3
x = 64
2x + 1 ➡ 2 × 64 + 1 = 129°
x - 13 ➡ 64 - 13 = 51°
Answer:
Step-by-step explanation:
Given the expression in the form , we know that Victoria can simplify it by adding the like terms:
She can also factor out -6:
Now, she needs to factor the coefficient of the second term rewrite it as (1-2), then:
Now she needs to group the terms as following:
And factor out 2x:
Finally, she has to factor out . Therefore, she gets:
x=-6, y=-3, z=-5
|x|+|y+z|=|-6|+|-3-5|=6+|-8|=6+8=14
