A girl is half as old as her sister and is also two years younger than her brother. If the sum of the three children's ages is 34 years, what is the product of their ages?
ASAP pls
Answer:
1280
Step-by-step explanation:
Let x represent the age of the girl then...
Brother: x+2
Sister: 2x
We can use this to set up an equation:
x+x+2+2x=34
Combine like terms
4x+2=34
Subtract 2 from both sides
4x=32
Divide both sides by 4
x=8 (girl)
x+2=10 (brother)
2x=16 (sister)
Now, we multiply these three numbers to get the product of their ages.
8(10)(16)=80(16)=1280

For a science project, Mrs. William’s third grade class kept track on how many days it rained during the month of April. The chart below shows their results. What percentage represents the fraction of days it rained on April?
(It rained 12 days in April, and it did not rain for 18 days in April.)
Answer:
40%
Step-by-step explanation:
Step one:
Add together both when it rained and when it didn't
12 + 18 = 30
Step 2:
You are then going to divide the number of days it rained by the total amount of days are in April. (We got this by adding the two numbers above)
12/30
It will then give you the solution of 0.4
You are then going to move the decimal two places to the right.
This will give you 40%

A few tips...
Tip #1: When the minuend and the subtrahend are negative, the result will always be negative.Tip #2: When the multiplicand and the multiplier are negative, the result will always be positive.Tip #3: When the dividend and the divisor is negative, the result will always be positive.Given two values:
x = -118y = -114Option A: x + y
x + y=> -118 - 114=> (Will be negative because of Tip #1)Option B: x - y
x - y=> -118 - (-114)=> -118 + 114=> -4 (negative)Option C: x • y
x • y=> -118 • -114=> (Will be positive because of Tip #2)Option D: x/y
-118/-114=> (Will be positive because of Tip #3)Hence, Option A and B is correct.

Saskia is solving an equation in one variable and gets the equivalent equation 3=3. Assuming her work is correct, what can she conclude about the original equation?
Answer:
The second option is correct. There are infinitely many solutions.
Step-by-step explanation:
Let's use the equation x + 3 = x + 3
We can simplify this two ways: x = x, or 3 = 3
We can use any value of x so that both sides are equivalent to each other.
For example:
x + 3 = x + 32 + 3 = 2 + 35 = 5or
x + 3 = x + 3-3 + 3 = -3 + 30 = 0As you can see, both sides of the equations are always the same with any value of x.
