Answer:

2.4h+2.2

Step-by-step explanation:

4.5h-7.7+9.9-2.1h

To solve this problem, we need to combine like terms.

Because 2.1h is negative, we can subtract it from 4.5h and get 2.4h.

2.4h-7.7+9.9.

We can do the same thing with -7.7 and 9.9. 9.9-7.7=2.2. We have to stop there because constants, numbers without variables, can't be added or subtracted to coefficients, numbers with variables.

Therefore, the simplified equation is 2.4h+2.2.

5.37 + x =12.89 explanation please it’s two step equation
Wewaii [24]

Answer:

7.52

Step-by-step explanation:

5.37 + x = 12.89

In order to solve this equation, we must isolate the variable, x.

1.) To do this, subtract 5.37 on both sides of the equation.

5.37 + x = 12.89

-5.37         -5.37

x = 7.52

Therefore, x = 7.52

Evaluate the expression for the given value of the variables.
Rudik [331]

Since c=15 and d=3, we replace the c and d variables with 15 and 3.

0.5x15-1.7x3

0.5x15=7.5

1.7x3=5.1

Now subtract.

7.5-5.1=2.4

hope it helps
