Answer:128
Step-by-step explanation:
C=number of acres of corn
w=number of acres of wheat
total is 180 acres
c+w=180
wants to plant 3 times as many corn as wheat
c=3w
subsitute 3w for c in other
c+w=180
3w+w=180
4w=180
divide boh sides by 4
w=45
sub back
c=3w
c=3(45)
c=135
135 acres of corn and 45 acres of wheat
Answer:
see below (I hope this helps!)
Step-by-step explanation:
Whole numbers are the integers that are greater or equal to 0. Basically, they are 0, 1, 2, 3....
Rational numbers can be written in the form a / b (where b ≠ 0 and a and b are integers (integers are ..., -1, 0, 1, ...))
Therefore, 4 rational numbers that are not whole numbers could be -5, -1, 0.5, and 3/4.

Slope-Intercept Form: y = mx + b
- m - slope
- b - y-intercept
Step-by-step explanation:
<u>Step 1: Define</u>
[Standard Form] 5x + 5y = 35
<u>Step 2: Rewrite</u>
<em>Find slope-intercept form.</em>
- Subtract 5x on both sides: 5y = -5x + 35
- Divide 5 on both sides: y = -x + 7
Answer:
60 for both
Step-by-step explanation:
Since these angles are parallel, they are equal to each other :
6x = 5x + 10
Subtracting 5x from both sides gives us :
x = 10
Substituting this value back into both angles gives us
6x = 60
5x+10 = 60
