Answer:
A is the correct answer
Step-by-step explanation:
If you plug y=x+10 in for the Y variable you just have to solve by multiplying.
1.) It should look like this:
2x + 3(x +10) = 40
2.) You will distribute the three which will make the equation look like this:
2x + 3x + 30 = 40
3.) Add like terms. Then subtract 30 from both sides. Then divide 5 by both sides to get the variable x alone.
Hope that helps
Answer:
by hand because hand solution can be done by mind and can be written in copy but in calculator to solve one problem the first should delete but in copy we can write and remember.
Circumference formula: 2πr
2 multiply the π by the radius which will be 4.5 because to get the radius u will have to to do 9 divide 2 which will be 4.5.
Calculate that in the calculator and you’ll get:
C=28.3 ( I rounded to the nearest tenth)
ANSWER: m > -4
Steps:
-3m + 18 < 30
-3m < 12
m > -4
(The sign flips when you divide the number w/ a letter (in this case ‘m’) by a negative number)
