Answer:
a=-13
Step-by-step explanation:
-50=6a+28
isolate the a
-50-6a=28
-6a=28+50
-6a=78
divide both sides by -6
a=-13
Could a triangle have angle measures of 94°, 106°, and 11° EXPLAIN HOW YOU KNOW.
Answer:
Nope
Step-by-step explanation:
All angles have to measure up to where adding up two of any angles will result in a number greater than or equal to the angle that was not added.
But here if we add up 94° and 11°, we end up with 105°.
Since 105° is lower than the angle not added, which is 106°, this triangle cannot exist.

A hockey team plays 42 matches. It wins 21, draws 14 and loses the rest. Express each of these results as a percentage of the total number of games played.
Express the number of each result as a fraction of the total number of games played and multiply with 100.
The percentage of the games won is :21/42 × 100 = 50%The percentage of the draw games is :14/42 × 100 = 100/3 = 33 1/3%The percentage of the games lost is :42-21-14/42 × 100 = 7/42 × 100 = 50/3 = 16 2/3%Enrique wants a skateboard that cost $68.00.

Meg is a veterinarian. She found that 33% of the 21 dogs she saw this week were boxers.Steve is also a veterinarian. He found that 10,or 50% he saw this week were boxers.Does each person need to find the part, the whole, or the percent? Meg needs to find the?
Answer:
a. Meg needs to find the part
b. Steve needs to find the percent.
Step-by-step explanation:
The question is incomplete.
This is the complete question:
Meg is a veterinarian. In a given week, 50% of the 16 dogs she saw were Boxers. Steve is also a veterinarian. In the same week, 7 of the 35 dogs he saw this week were Boxers. Each wants to record the part the whole, and the percent.
a. Does Meg need to find the part, the whole, or the percent.
b. Does Steve need to find the part, the whole, or the percent.
Solution to the problem
a. Does Meg need to find the part, the whole, or the percent.
Meg already knows the whole and the percent.
The whole is the entire number of dogs seen: 16 dogs.
The percent is 50%.
Hence, she needs to find the part: this is how many (what part) of the 16 dogs she saw were boxers.
And she can do with a simple operation:
Part = whole × percent = 16 × 50% = 8. This is 8 dogs of 16 were boxers.
b. Does Steve need to find the part, the whole, or the percent.
He already knows the part (7 of the 35 dogs were boxers) and the whole (35 dogs).
Then he needs to find the percent, which he can do using the next operation:
Percent = (part / whole) × 100 = (7/35)×100 = 20%

Step-by-step explanation:
The question is how long will he go in 3 hours and 45 minutes.
3 hours and 45 minutes is equal to 3.75 house 45/60=3/4 75/100=3/4
So multiply 3.75 by 80 for 300

6y - 5 = 7y - y what does y equal
show how you did it pls
Answer: y is a false statement
Step-by-step explanation: put all the y terms on one side and all the constants on the other. i'm going to move all the y terms to the right and the constants to the left. on the left we have a -5 leftover and on the right it would be 7y-y-6y. if you add those terms together, you're left with -5=0 which is not possible. y is a false statement

Victoria has a cow. The cow’s tail is 3 inches long. The cow’s tail grows by 5 inches every 6 months. What will the tail’s length be next year?
Answer:
The cow's tail will grow 25 inches more intotal
The cows tail will be 28 inches long.
Step-by-step explanation:
12 months equals to one year (leap year not included) cows tail
grows 5 inches every 6 months. So, 5 x 5 = 25 + the 3 inches from its previous tail will give us total for all. so the answer is 28 in all or 25 for how much it has grown.
That's a long tail ;-;
Amy has 1275 less than her brother ben .then ben spends 550 and amy gets 750 . who has more money now?
Amy because Ben spend the less money then
amy get more money
Amy has more money than her brother after all transactions.
What is an equation and an expression?An equation is a statement that the depicts the values of two mathematical expressions as equal using an (=) sign. Example -
2x = 5
An expression is written using individual terms (either constant or variable) separated by mathematical operations. Example -
3x + 5y + 3
We have Amy who has $1275 less than her brother ben. Ben spends $550 and Amy gets $750.
Assume that the money with Ben and Amy after transactions is $x and $y respectively. Let Ben has a initial amount of $m and Amy has of $n.
n = m - 1275
After transactions -
x = m - 550
y = m - 1275 + 750 = m - 525
Now -
m - 525 > m - 550 for every value of [m].
So, now Amy has more money.
Therefore, Amy has more money than her brother after all transactions.

Answer:
1st one: x = -2
2nd one: x = -4
Step-by-step explanation:
1. Step 1: Rewrite into an equation.
[tex](6x+44) + (-10x+65) = 117[/tex] [tex]6x + 44 - 10x + 65 = 117[/tex]Step 2: Simplify both sides of the equation.
[tex](6x-10x) + (44+65) = 117[/tex] [tex]-4x + 109 = 117[/tex]Step 3: Subtract 109 from both sides.
[tex]-4x + 109 - 109 = 117-109[/tex] [tex]-4x = 8[/tex]Step 4: Divide both sides by -4.
[tex]\frac{-4x}{-4}=\frac{8}{-4}[/tex] [tex]x = -2[/tex]Therefore, x = -2 for the first one.
2. Step 1: Rewrite into an equation.
[tex]-16x + 13 - 20x + 23 = 180[/tex]Step 2: Simplify both sides of the equation.
[tex](-16x-20x)+(13+23)=180[/tex] [tex]-36x +36 = 180[/tex]Step 3: Subtract 36 from both sides.
[tex]-36x + 36 - 36 = 180 - 36[/tex] [tex]-36x = 144[/tex]Step 4: Divide both sides by -36.
[tex]\frac{-36x}{-36} = \frac{144}{-36}[/tex] [tex]x = -4[/tex]Therefore, x = -4 for the second one!
Denise bought a T-shirt at the sale price of $21.08. This represents a 15% decrease in price. What was the original price of the shirt?
Answer:
100% - 15 % = 85 %
So, $21.08 represents the 85% sale price
What number represents the other 15% of the original price?
(21.08 x 15) / 85 = 3. 72
$21.08 + $3.72 = $24.80 which is the original price.
