Answer:
x = -6
Step-by-step explanation:
-2x - 9 = 3
solve for x by inverse operations
-2x - 9 = 3
+9 +9
-2x = 12
/-2 /-2
x = -6
how do I convert -15 4/9 to a decimal?
Answer:
-15.44...
Step-by-step explanation:
Well the -15 is a whole number so it stays on the left of the decimal. Then you divide 4 by 9 and get 0.4444... Lastly you just add them together.

C
Step-by-step explanation:
I substituted the x value with the different options. I kept doing that until the equation made sense.
Answer:
b) x = 7
Step-by-step explanation:
16+5x = x+12
Subtract 16 from both sides
5x = x+28
subtract x from both sides
4x = 28
divide 4 from both sides
x = 7

Help anyone ? I really don’t understand it .
Han and Tyler are following a polenta recipe that uses 5 cups of water for every 2 cups of cornmeal.
1 * Han says, “I am using 3 cups of water. I will need 115 cups of cornmeal.”
2 * Tyler says, “I am using 3 cups of cornmeal. I will need 712 cups of water.”
Do you agree with either of them? Show your reasoning.
Answer:
No
Step-by-step explanation:
1. 5 cups of cornmeal=2 cups of water. Using 115 cups of cormeal would mean you need 287.5 cups of water, not 3.
3 is too little
2: If you use 5 cups of water for every 3 cups of cornmeal, for 3 cups of cornmeal you'd need like 6.5 cups of water, not that high of a number.
As the given reasoning 3 cups of water is very less than both the statements are not appropriate.
What is an expression?Mathematical actions are called expressions if they have at least two terms that are related by an operator and include either numbers, variables, or both. Adding, subtraction, multiplying, and division are all reflection coefficient operations. A mathematical operation such as reduction, addition, multiplication, or division is used to integrate terms into an expression.
As per the given reasoning in the question,
1. 2 cups of water to 5 cups of cornmeal. Instead of 3, you would use 287.5 cups of water if you used 115 cups of cornmeal.
2. If you are using 5 cups of water for every 3 cups of cornmeal, you would need 6.5 cups of water, which is not a particularly high quantity.

What is the best estimate of the sum of the fractions?
StartFraction 31 over 4 EndFraction + StartFraction 17 over 3 EndFraction + StartFraction 8 over 18 EndFraction
Answer:
Let's add the fractions first and then we can estimate the sum.
= 31/4 + 17/3 + 8/18
change to common denominators
= 279/36 + 204/36 + 16/36
add numerators only
= 499/36 or 13 31/36 or 13.86
ANSWER: (B) 13 is the best estimate of the answer. Normally we round up to 14 with a number like 13.86, but since that is not a choice, we can estimate 13 as the answer.

A submarine is exploring the Pacific Ocean. At 502.5 feet below sea level, the water temperature is 63 1/4°F. The submarine dives down 115 feet deeper, and the water temperature drops by 2 1/5 °F. What were the elevation and the water temperature after the submarine dove? Assume that sea level is at 0 feet of elevation.
Write an expression to represent the water temperature after the submarine’s final dive. Then simplify the expression to find the temperature.
Answer:
At the elevation 617.5 feet below the sea level temperature of the water was 61\frac{1}{20}°F
Step-by-step explanation:
At 502.5 feet below the sea level temperature of the water is 63\frac{1}{4}°F
When submarine dives down 115 feet deeper, water temperature drops by 2\frac{1}{5}°F
Elevation after the submarine dove = -502.5 - 115 = -617.5 feet
This negative sign represents the elevation below the sea level.
And the temperature will be = 63\frac{1}{4}-2\frac{1}{5}
= \frac{253}{4}-\frac{11}{5}
= \frac{1265-44}{20}
= \frac{1221}{20}
= 61\frac{1}{20}°F
Therefore, at the elevation 617.5 feet below the sea level temperature of the water was 61\frac{1}{20}°F
The required expression is y = 0.01x + 58.2. Where, x = level of sea and y = temperature. At 115 feet deeper temperature is 61 1/4°F.
A submarine is exploring the Pacific Ocean. At 502.5 feet below sea level, the water temperature is 63 1/4°F.
It is the relationship between sets of values. e g y=f(x),
Here, assume that relation ship between temperature and sea level is linear. So the expression can be calculated as y = - 0.01x + 58.2.
Since at 115 feet deeper from 502.5 temperature-
total sea level; = 502.5+115
= 617.5
Put it in expression
y = -0.01 * 617.5 + 68.2
y = 61.25
y = 61 1/4 °F
Thus, the required expression is y = 0.01x + 58.2. Where, x = level of sea and y = temperature. At 115 feet deeper temperature is 61 1/4°F.
