gabriel saves 40% of his monthly paycheck for collage. he earned $270 last month.how much money did gabriel save for collage
rusak2 [61]
The best thing to do is to find 10%, and you can do this by dividing $270 by 10, and therefore, $27 is equal to 10%. To find 40%, you've got to multiply $27 by 4, and this gives you $108. Therefore, gabriel saved $108 last month :)

Can anyone help me with Qs 9-14 pls
lions [1.4K]

Answer:

Step-by-step explanation:

angle 2 and angle 3 are linear pair

angle 1 and angle 7 are alternate exterior angle

angle 4 + angle 7=a80 degree

124 + angle 7=180

angle 7=180-124

angle 7=56 degree

angle 1 is supplementary to angle 2 ,angle 4, angle 6, angle 8 .In supplementary angle sum of two angle is always 180 degree.

angle 4 and angle 5 are supplementary angles because their sum is equal to 180 degree.

angle 4 + angle 5(being co interior angle)

3x+17+x+23=180

4x+40=180

4x=19=180-40

x=140/4

x=35

What is the slope of a line parallel to the line whose equation is 8x — 10y = –60.
irina1246 [14]

Answer:

4/5

Step-by-step explanation:

If two lines are parallel, then they have the same slope. So, we first need to put the equation in slope intercept form (y = kx + b)

8x - 10y = -60

-10y = -8x - 60

y = 4/5x + 6

So the slope is 4/5.
