Answer:
x=-10, y=-20
Step-by-step explanation:
Since both 2x and 3x+10 equals y, they equal each other.
2x = 3x + 10
x = -10
Substitute -10 for x
2(-10) = y
y=-20
The correct one is: 22 of the courses Nina passed were worth 3 credits each.
Because 22 multiplied by three is 66. 40-22 is eighteen. Then you would multiply 18 and 4 together to get 72. 72+66 is 138.
We first write the fractions in their decimal forms and find out the ratio.
2 1/4 is equivalent to 2.25, and 1 1/3 is equivalent to 1.33.
Ratio will be 2.25 / 1.33 = 1.69 or 1.7 rounded off. Since it cannot be simplified further, then the ratio of mulch to gravel will be 1.7: 1.
Quantity of mulch sold → 1.7/2.7 of 172 →0.629 ×172 = 108.2 pounds.
Quantity of gravel sold will be 172 -108. 2 = <span>63 .8 pounds.</span>
