Answer:
x = 11/3 = 3 2/3
y = 13/3 = 4 1/3
Step-by-step explanation:
Here, we want to solve the system of equations simultaneously
x + y = 8
2x -3 = y
From the second equation, we have an equation for y
we can simply proceed to substitute this into the first equation
x + 2x - 3 = 8
3x - 3 = 8
3x = 8 + 3
3x = 11
x = 11/3
Recall;
y = 2x - 3
y = 2(11/3) - 3
y = 22/3 - 3
y = (22-3(3))/3
y = (22-9)/3 = 13/3
Answer:
8 cups = 2 quarts
Step-by-step explanation:
90 degrees plus 49 degrees is 139 degrees 180 degrees minus 139 degrees = 41 degrees
90+49=139
180-139= 41
answer 41 degrees
Answer: x is 45, y is 80
Step-by-step explanation:
subtract the angles surrounding x (70 - 25 = 45)
add 45 + 55 to get 100
the entire triangle has to equal 180 degrees, so subtract 100 from 180 to get the value of y
