Ok send the picture so I can help you.
Answer:
Step-by-step explanation:
if the question is
-7p * -4r * 39
then it's
-1*-1*7*4*39*p*r
now you just need a calculator to find the numbers that are multiplied together
-1 * -1 = 1
7*4=28
28*39*p*r
1092*p*r
1092pr
Answer:
a = 18.15
Step-by-step explanation:
Combine like terms on the left side of the equation first. Add 7 and 42, then subtract 32 from the answer you get, then subtract 32 from that answer. This is going by order of PEMDAS.
Remember PEMDAS: (numbers 3 & 4 and numbers 5 & 6 are solved from left to right)
- Parentheses
- Exponents
- Multiplication
- Division
- Addition
- Subtraction
After combining like terms on the left side, you get -15. Now combine like terms on the right side of the equation by adding 14.3 and 7.
Get -2a alone by subtracting 21.3 from both sides.
Divide both sides by -2.
In this equation, a should equal .
X - 11 = 16
x = 16 + 11
x = 27
hope this helps!
