Answer:
<u>The value of x is 11 and CE = 40 and AC = 60</u>
Step-by-step explanation:
Δ ΑΒC ≅ Δ EDS, therefore we have that:
24 / 36 = 3x + 7 / 6x - 6
Solving for x,
24 * (6x -6) = 36 * (3x + 7)
144x - 144 = 108x + 252
144x - 108x = 252 + 144
36x = 396
x = 396/36
x = 11 ⇒ 3x + 7 = 33 + 7 = 40; ⇒ 6x - 6 = 66 - 6 = 60
<u>The value of x is 11 and CE = 40 and AC = 60</u>
Answer:
The answer is 20
Step-by-step explanation:
From the graph it shows that J is located at point 15, and Q is located at point 35
If we move 20 units from point J to point Q, we land at point Q, making it the distance they are from one another.
Answer:
4
Step-by-step explanation:
This situation has two unknowns - the total number of half dollars and the total number of quarters. Because we have two unknowns, we will write a system of equations with two equations using the two unknowns.
- h+q=31 is an equation representing the total number of coins
- 0.50h+0.25q=11 is an equation representing the total value in money based on the number of coin. 0.50 and 0.25 come from the value of a half dollar and quarter individually.
We write the first equation in terms of q by subtracting it across the equal sign to get h=31-q. We now substitute this for h in the second equation.
0.50(31-q)+0.25q=11
15.5-0.50q+0.25q=11
15.5-0.25q=11
After simplifying, we subtract 15.5 across and divide by the coefficient of q.
-0.25q=-4.5
q=4
We now know of the 31 coins that 4 are quarters.
