Answer:

No solutions

Step-by-step explanation:

4(-8x + 5) = -32x - 26

Expanding the parentheses:

-32x+20=-32x-26

Adding 32x to both sides:

20=-26

This equation has no solutions, because these two are not equal. Hope this helps!

Step-by-step explanation:

Marco makes his famous salad Jackson by mixing 5 1/4 ounces of olive oil with 1 1/2 ounces of vinegar.

Olive oil Vinegar

5 1/4 1 1/2

28 x

Write a proportion:

$\dfrac{5\frac{1}{4}}{28}=\dfrac{1\frac{1}{2}}{x}\\ \\5\dfrac{1}{4}\cdot x=28\cdot 1\dfrac{1}{2}\ [\text{Cross multiply}]\\ \\\dfrac{21}{4}x=28\cdot \dfrac{3}{2}\\ \\\dfrac{21 x}{4}=42\\ \\x=42\div \dfrac{21}{4}\\ \\x=42\cdot \dfrac{4}{21}\\ \\x=2\cdot 4\\ \\x=8\ ounces$

Marco will make

$28+8=36$ ounces of dressing

victus00 [196]

Answer:

Part a) The temperature at noon was -3°F

Part b) The temperature at 3:00 pm was +2°F

Part c) The temperature at 11:00 pm was -6°F

Step-by-step explanation:

The complete question is

When Leo woke up he saw that the temperature was -8°F. By noon the temperature has increased 5°F. Part a) What was the temperature at noon?

Part b) By 3:00 pm, the temperature increased by another 5 degrees Fahrenheit was the temperature at 3:00 pm positive or negative?

Part c) By 11:00 pm, the temperature had dropped 8°F. Was the

temperature at 11:00 PM positive or negative? Explain.

Part a) we know that

You can use a number line to adds the numbers

-8+5=-3°F

therefore

The temperature at noon was -3°F

Part b) we know that

the temperature increased by another 5 degrees

You can use a number line to adds the numbers

-3+5=+2°F

therefore

The temperature at 3:00 pm was +2°F

Part c) we know that

the temperature had dropped 8°F

You can use a number line to adds the numbers

2-8=-6°F

therefore

The temperature at 11:00 pm was -6°F

The coastline of the United States is 12,383 miles long Canada coastline is 113,211 miles longer than the coastline of the Unite

jek_recluse [69]

125,594 miles. Canada coastline (x) - U.S. Coastline (12,383) = 113,211.
x - 12,383 = 113,211
x - 12,383 + 12,383 = 113,211 + 12,383 (by addition property of equality)
x = 113,211 + 12,383
x = 125,594
Basically, you add the two given numbers together.
