Answer:
2(3x+10) = 6x+20
6x+20 = 6x+20
6x = 6x
x = x
This has an infinite amount of solutions
Step-by-step explanation:
3x+x=96
(4x=96)/4
x=24
3(24)=72
Hector is 24 and his grandma is 72.

Answer:
.0417
Step-by-step explanation:
.0 is 10th's place so if we had 50 percent it would be .5
.00 is ones place so 4 percent would be .04
.0000 is where fractions come in so 3 3/4 would be .00375
6 + (2 - 3 (4) )+1 / (5) (2) - 4 = -1 /2
<u>Step-by-step explanation:</u>
6 + (2 - 3 (4) )+1 / (5) (2) - 4
Using the BODMAS rule, we can simplify the expression in the following way, like, we have to do the operation inside the brackets first, then division, multiplication, addition and then subtraction.
= 6 + (2 - 3 (4) )+1 / (5) (2) - 4 [operation inside the brackets]
= 6 + (2 - 12) )+1 / (5) (2) - 4
= 6 + (-10) )+1 / (10) - 4
= 6 + 1 -10 / (10) - 4
= 7 - 10/ 6
= -3 / 6
= -1/2
D=13
d=-5+3 times erin
13=3e-5
add 5 to both sides
18=3e
divide by 3
6=e
erin=3
