How to find the x intercept of 3y=2x-6: (when y is 0)
3(0) = 2x - 6
0 = 2x - 6
+6 + 6
-------------------------
6 = 2x
------ -----
2 2
x = 3
How to find the y intercept of 3y=2x-6: (when x is 0)
3y = 2(0) - 6
y = 0 - 6
3y = -6
------ -----
3 3
y = -2
Answer:
32 muffins
Step-by-step explanation:
one cup of milk will make 32 muffins
you can set up a proportion of milk/muffins = milk/muffins
let 'x' = number of muffins made from one cup of milk
5/8 ÷ 20 = 1 ÷ x
cross-multiply to get 5x = 20(8)
5x = 160
x = 32
Answer:
<em>Measure of angle B: 76°</em>
<em>Measure of angle C: 76°</em>
<em>Measure of angle A: 28°</em>
Step-by-step explanation:
<u>Equations</u>
Let's call
x = measure of angle B
Since angle B is congruent with angle C:
x = measure of angle C
The sum of the angles in a triangle is 180°:
180 - x - x = 180 - 2x = measure of angle A
It's given the measure of angle B is 20 more than twice the measure of angle A, thus:
x = 20 + 2(180 - 2x)
Operating the parentheses:
x = 20 + 360 - 4x
Adding 4x:
5x = 380
Dividing by 5:
x = 380/5
x = 76°
Measure of angle B: 76°
Measure of angle C: 76°
Measure of angle A: 180 - 2*76°= 28°
Answer:
75+(-50)=75-50
Step-by-step explanation:
-let x be the profit made last week and y be the profit made this week.
-The two week profit/ loss is given as:
#We substitute actual values to calculate the profit/loss made:
Hence, the two-week combined profit is $25.00
