Yolanda’s bowling average for 2 games was 138. Her second game score was 8 points lower than her first game score. Which system of equations will determine Yolanda’s scores for her first game, f, and her second game, s?
Answer:
║⊕║Hello Wonderful Person║⊕║
This should be your answer:
So first let us solve 138 divided by 2. Which equals 69. So right now, each game Yolanda did was 69 points. But, it says her second game score was 8 points lower. But it still has to be 138 points. So, you take away 8 points from S-69 (second game) and add 8 to F-69(First game) Which will equal 61 for S and 77 for F. So the answer is,
Yolanda's first game (F) was 77 points.
Yolanda's second game (S) was 61 points.
In total she scored 138 points.
Step-by-step explanation:
I hope this helped!
(brainliest appreciated!)
First answer!! :DHave a wonderful and blessed day!Yolanda’s scores for her first game, f is 73, and her second game, s is 65
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Yolanda’s bowling average for 2 games was 138.
f+s=138....(1)
Her second game score was 8 points lower than her first game score.
s=f-8....(2)
Substitute 2 in 1.
f+f-8=138
2f-8=138
Add 8 on both sides
2f=138+8
2f=146
Divide both sides by 2
f=73
s=73-8
s=65
Hence, Yolanda’s scores for her first game, f is 73, and her second game, s is 65

Each of 7 kittens, weighs less than 3.5 ounces. Find all the possible values of the combined weights of the kittens. 7th grade math please help, also just need the answer no explanation thx
Answer:
Let's use w to symbolize the weight of kittens. Given by the statement "each kitten weighs less than 3.5 ounces" we know that
1*w < 3.5
We can multiply both sides of the inequality by 7 to determine the total weights
7*(1*w) < 7*(3.5)
7*w < 24.5
Since there are 7 kittens, the combined weight of the kittens is 7w, therefore the above expression could be read as "The combined weight of the kittens is less than 24.5 ounces"
Answer:
7*(1*w) < 7*(3.5)
Step-by-step explanation:
Let's use w to symbolize the weight of kittens. Given by the statement "each kitten weighs less than 3.5 ounces" we know that
1*w < 3.5
We can multiply both sides of the inequality by 7 to determine the total weights
7*(1*w) < 7*(3.5)

Simplify negative 3 over 4 divided by 2 over negative 8.
Answer:
3Step-by-step explanation:
−3/4÷2/−8=?
In the second fraction, move the negative sign from the denominator to the numerator and the value remains the same.
The equivalent equation is
−3/4÷ −2/8=?
Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.
Take the reciprocal of the second fraction by flipping the numerator and denominator, leaving the negative sign on the numerator, and changing the operation to multiplication. Then the equation becomes
−3/4× −8/2=?
For fraction multiplication, multiply the numerators and then multiply the denominators to get
−3× −8/4×2= 24/8
Since 24 divided by 8 equals 3 then,
24/8 =3
Therefore:
−3/4÷ 2/−8= 3

Mai’s backpack weighs 9 pounds. Han’s backpack weighs 8.3 pounds. Priya’s backpack weighs 7.75 pounds, and Kiran’s backpack weighs 6.125 pounds. Select all the true statements.
Group of answer choices
Han’s backpack is 2.175 pounds heavier than Kiran’s.
Mai’s backpack is 2.25 pounds heavier than Priya’s.
Han’s backpack is 16.05 pounds heavier than Priya’s.
Kiran’s backpack and Han’s backpack together weigh 14.3125 pounds.
The backpacks weigh 31.175 pounds together.
Answer: Han’s backpack is 16.05 pounds heavier than Priya’s.
Step-by-step expl
The true statements are:
Han’s backpack is 2.175 pounds heavier than Kiran’s.
The backpacks weigh 31.175 pounds together.
Here, we have,
Let's evaluate each statement:
Han’s backpack is 2.175 pounds heavier than Kiran’s.
To check if this statement is true, we need to find the difference between the weights of Han's and Kiran's backpacks:
Han's backpack weight - Kiran's backpack weight = 8.3 - 6.125 = 2.175
The difference is indeed 2.175 pounds, so this statement is true.
Mai’s backpack is 2.25 pounds heavier than Priya’s.
Similarly, we find the difference between the weights of Mai's and Priya's backpacks:
Mai's backpack weight - Priya's backpack weight = 9 - 7.75 = 1.25
The difference is 1.25 pounds, not 2.25 pounds. Therefore, this statement is false.
Han’s backpack is 16.05 pounds heavier than Priya’s.
Again, we calculate the difference between Han's and Priya's backpack weights:
Han's backpack weight - Priya's backpack weight = 8.3 - 7.75 = 0.55
The difference is 0.55 pounds, not 16.05 pounds.
Thus, this statement is false.
Kiran’s backpack and Han’s backpack together weigh 14.3125 pounds.
To check this statement, we add the weights of Kiran's and Han's backpacks:
Kiran's backpack weight + Han's backpack weight = 6.125 + 8.3 = 14.425
The sum is 14.425 pounds, not 14.3125 pounds.
Hence, this statement is false.
The backpacks weigh 31.175 pounds together.
To verify this statement, we add the weights of all four backpacks:
Mai's backpack weight + Han's backpack weight + Priya's backpack weight + Kiran's backpack weight = 9 + 8.3 + 7.75 + 6.125 = 31.175
The sum is indeed 31.175 pounds, so this statement is true.
In conclusion, the true statements are:
Han’s backpack is 2.175 pounds heavier than Kiran’s.
The backpacks weigh 31.175 pounds together.
