2x-3x=5+10

-x=15

X=-15

2x+1=0.... 1

X-1=0

X=1......2

Answer:

Jacob: 4
his mother: 39

Step-by-step explanation:

Let J and M represent the current ages of Jacob and his Mother.

currently:

M = 3 +9J

in 11 years:

M+11 = 5 +3(J+11)

Using the first equation to substitute for M in the second, we have ...

(3 +9J) +11 = 5 +3(J +11) . . . . . substitute for M

9J +14 = 3J +38 . . . . . . simplify

6J + 24 . . . . . . . . . . subtract 3J+14

J = 4 . . . . . . . . . . divide by 6

M = 3 +9(4) = 39

Jacob is 4 and his mother is 39.

A bicycle manufacturing company makes a particular type of bike. Each child bike requires 4 hours to build and 4 hours to test.

Bess [88]

Answer:

$4c+6a\leq120\\\\4c+4a\leq100$

Step-by-step explanation:

Let c represents child bikes and a represents adult bikes.

Given : Each child bike requires 4 hours to build and 4 hours to test. Each adult bike requires 6 hours to build and 4 hours to test.

With the number of workers, the company is able to have up to 120 hours of building time and 100 hours of testing time for a week.

Then, the required system of inequality :-

$4c+6a\leq120----(1)\\\\4c+4a\leq100-----(2)$

If company make 10 child bikes and 12 adult bikes in the week.

Then Put c=10 and a=12 bikes in (1) and (2).

$4(10)+6(12)=40+72=112\leq120$ ⇒Bike order meets the restrictions

$4(10)+4(12)=40+48=88\leq100$ ⇒Bike order meets the restrictions

Hence, the system of inequality best explains whether the company can build 10 child bikes and 12 adult bikes in the week.

$4c+6a\leq120\\\\4c+4a\leq100$
