Identifying a Number to Multiply by When Using the Linear Combination Method
Warm-Up
Match each system to the number the first equation can be multiplied by to eliminate the
x-terms when adding to the second equation.
3x - 8y = 1
6x + 5y = 12
-2.
10x - 4y = -8
–5x + 6y = 10
1/2
-2x + y = 3
4x + 3y = 9
-1/2
-8x + 10y = 16
-4x - 5y = 13
2.

answer: d. $20

step-by-step explanation:

just took the test

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
