Answer:
b a moderately active man wiighing
S=sophies age
l=llucas age
j=jessica's age
j is 6 times of s
j=6s
s is 2 years more than l'
s=2+l
in six years means everybody +6
j+6 is 4 times (l+6)
j+6=4(l+6)
the equations are
j=6s
s=2+l
j+6=4(l+6)
you would subisutte
6s+6=4(l+6)
6(2+l)+6=4(l+6)
undistribute the 2 in each
2(3(2+l)+3)=2(2(l+6))
divide both sides by 2
3(2+l)+3=2(l+6)
distribute
6+3l+3=2l+12
add like terms
9+3l=2l+12
subtract 9 from both sides
3l=2l+3
subtract 2l from both sides
l=3
therefor
s=2+l
s=2+3=5
s=5
6s=j
6(5)=j
j=30
lucas=3
sophie=5
jessica=30
To find the tax rate when given the initial price of an object and the final tax value, you use the equation: $350 * X = $22.75 (where X is the sales tax rate). Then solve:
$22.75/$350 = .065
So the rate is 6.5%
To solve for variables in an equation, we simply need to isolate the variable and simplify all other terms. We can do this by performing the opposite operation on the values.
x/6+4=15
-4 -4
x/6=11
*6 *6
x=66
Using the math above, we can see that x=66.
