Answer:
x = 5
Step-by-step explanation:
Since both triangles are similar hence;
m<CAB = m<CDE
Given theta
m<CAB = 50degrees
m<CDE = 10x
Substitute the given angles
50 = 10x
Swap
10x = 50
Divide both sides by 10
10x/10 = 50/10
x = 5
Hence the value of x is 5
Answer:
Step-by-step explanation:
Let x represent the number of vehicles that the sales person sold in a month.
The sales person at the car dealership earns a monthly salary of $2400 and $250 for each vehicle sold. Let y represent the total amount he earns for selling x vehicles in a month. Therefore,
y = 250x + 2400
To determine the number of vehicles that the sales person needs to sell in a month to earn exactly $4000, we would substitute
4000 for y. It becomes
4000 = 250x + 2400
250x = 4000 - 2400 = 1600
x = 1600/250
x = 6.4
He would have to sell 7 vehicles because he cannot sell 6.4 vehicles and if he sells 6 vehicles, it would be lesser than $4000
Answer:
56n - 35
Step-by-step explanation:
6n + 5(10n - 7) ← multiply each term in the parenthesis by 5
= 6n + 50n - 35 ← collect like terms
= 56n - 35
