please help mee!! will mark brainliest! "the Kuna Caveman football team won 75% of their games. If they won 9 games, how many games did they play?"
Answer:
12 games
Step-by-step explanation:
Let x be the number of games played
The y won 75% of the games played and that was 9
x * 75% = 9
Change to decimal form
x * .75 = 9
Divide each side by .75
x * .75 /.75 = 9/.75
x =12
They played 12 games
Answer:
Step-by-step explanation:
75g/100=9
g=900/75
g=12
Gia receives an allowance of $2 a week and already has $20 in savings. Michael receives an allowance of $3 a week and already has $5 in savings. Gia and Michael both save their entire allowance. After how many weeks, will Gia and Michael have the same amount in savings? How much money will they have?
Answer:
After 15 weeks, Gia and Micheal will both have $50 in savings.
Step-by-step explanation:
For Gia:
We start at $20 since she already has $20 in savings, we will add that to how much Gia will receive in 15 weeks.
Gia receives $2 a week and therefore in 15 weeks she will have $50.
= 2x15 = $30
= 30+20 = $50
For Micheal:
We start at $5 since he already has $5 in savings, we will add that to how much Micheal will receive in 15 weeks.
Micheal receives $3 a week and therefore in 15 weeks he will receive $50
= 3x15 = $45
= 5+45 = $50

Find the value of x.
x
133°
133°
47°
[tex]\huge\underline\bold\blue{ƛƝƧƜЄƦ}[/tex]
Three angles are given to us and we all know that the sum of four sides of quadrilateral is 360⁰
so
133⁰ + 147⁰ + 47⁰ + x = 360⁰
x = 380⁰ - 367⁰
x = 13⁰

In a science experiment, Katrina needs to know the mass of a seed pod.
She measures the mass of 8 seed pods as 10.4g.
What is the mass of 1 seed pod?
Answer:
1.30g
Step-by-step explanation:
The mass of 8 seed pods is equal to 10.4g.
10.4g = 8 pods
Total mass / Total pods = Individual pod weight
10.4g / 8 pods = 1.30g per pod
Lets check our work to confirm:
1.30g x 8 pods = 10.4g

USE SYSTEMS BY SUBSTITUTION.
X=
Y=
Answer:
X=-2
Y=0
Step-by-step explanation:
X+y=-2 = x=-2-y
3x+4y=-6
3(-2-y)+4y=-6
-6-3y+4y=-6
y=0
x+3(0)=-2
x=-2
Answer:
[tex]\boxed {\boxed {\sf (-2,0)}}[/tex]
Step-by-step explanation:
To solve by substitution we must first isolate 1 variable in an equation.
Let's use the first equation.
[tex]x+3y= -2[/tex]
Subtract 3y from both sides to isolate the variable x.
[tex]x+3y-3y= -2 -3y[/tex]
[tex]x= -2 -3y[/tex]
Now we can substitute the expression (-2-3y) in for x in the second equation.
[tex]3x+4y= -6[/tex]
[tex]3(-2-3y)+4y= -6[/tex]
Distribute the 3. Multiply each term inside the parentheses by 3.
[tex](3*-2)+ (3*-3y)+4y=-6\\-6-9y+4y=-6[/tex]
Combine the like terms on the left side.
[tex]-6-5y= -6[/tex]
Add 6 to both sides to isolate the variable.
[tex]-6+6-5y=-6+6\\-5y=0[/tex]
Divide both sides by -5.
[tex]-5y/-5=0/-5 \\y=0[/tex]
Now we know that y is equal to 0 and can substitute it into the first equation and find x.
[tex]x+3(0)=-2[/tex]
[tex]x+0=-2 \\x= -2[/tex]
x is equal to -2 and y is equal to 0.

Dividend is equal to :
divisor * quotient - remainder
divisor , quotient
divisor x quotient + remainder
divisor * quotient x remainder
Answer:
divisor × quotient + remainder
Step-by-step explanation:
the dividend is the number thats going to be divided. (for example, 10 crayons divided by 2 people). the formula to find this would be multiplying the divisor by the quotient, and adding the remainder if there is one.
Dividend is equal to:
divisor × quotient - remainderdivisor , quotientdivisor x quotient + remainderdivisor × quotient x remainder✭ Explanation -:To solve this question first we should know the following terms :
[tex] \bull \: \small\sf{ Dividend}[/tex]
A number to be divided by another number.[tex] \bull \: \small\sf{ Divisor}[/tex]
A number by which another number is to be divided.[tex] \bull \: \small\sf{ Quotient}[/tex]
A result obtained by dividing one number by another.The formula for dividend is
[tex] \star \: \small \boxed{\sf{ Dividend = Divisor × Quotient + Remainder }}[/tex]
