Answer:

Step-by-step explanation:

ΔABC is congruent with ΔDEF. That means the corresponding sides are congruent.

Look at the order of the letters. EF are the last two letters of ΔDEF. So this corresponds with the last two letters of ΔABC. Therefore, EF ≅ BC.

EF ≅ BC

x² + 8x = 48

x² + 8x − 48 = 0

(x + 12) (x − 4) = 0

x = -12 or 4

Since x can't be negative, x = 4.

A salesperson earns a commission based on the number and type of vehicle sold. A person selling 6 cars and 3 trucks earns $4,800

madam [21]

4800 divide by 3=1600 (2 cars 1 truck)

4600-1600-3000 (6 cars)

3000 divide by 3 = 1000(2cars)

1000 times 2=2000(4 cars )

4800-2000-2800 (2 cars 3 trucks)

Eliminate the parameter. x = 1/2t, y = 3t^3 - 1

Elis [28]

X = t/2. t = 2x
y = 3t^3 - 1
y = 3(2x)^3 -1

y = 24x^3 -1

Explain (in words) what you would do to find the missing value in the equation. You do not find the missing number! Equation: ?

maks197457 [2]

Answer:

The missing value = $23\frac{1}{24}$

Step-by-step explanation:

Given - Equation: ? + 59 5/8= 82 2/3

To find - Explain (in words) what you would do to find the missing value in

the equation. You do not find the missing number.

Proof -

Let the missing number = x

So, the equation becomes x + $59\frac{5}{8}$ = $82\frac{2}{3}$

⇒x = $82\frac{2}{3}$ - $59\frac{5}{8}$

= $\frac{248}{3} - \frac{477}{8}$

= $\frac{1984 - 1431}{24}$

= $\frac{553}{24}$

= $23\frac{1}{24}$

⇒x = $23\frac{1}{24}$

∴ we get

The missing value = $23\frac{1}{24}$

Explanation -

Here we have given the ? with addition of number that is equation to some number.

We just have to subtract the two numbers to find the missing value , as we do above.
