5^2 + 3^2 (equals to 34) ; That's the wrong expression

It should look like this : (5+3)^2 (which equals to 64)

Identify the GCF of 6x^2y^2 − 8xy^2 + 10xy
myrzilka [38]

Answer:

The GCF for the numerical part is 2

Step-by-step explanation:

6x^2y^2-8xy^2+10xy

It contains both numbers and variables, there are two steps to find the GCF(HCF).

1). Find the GCF for the numerical part 6, -8,10

2). Find the GCF for the variable part x^2,y^2,x^1,y^2,x^1,y^3

3).Multiply the values together.

Find the common factors for the numerical part:

6,-8,10

Factors of 6

6: 1,2,3,6

Factors of -8

-8: -8,-4,-2,-1,1,2,4,8

Factors of 10

10:1,2,5,10

Common factors of 6,-8, 10 are 1,2

The GCF Numerical=2

The GCF Variable= xy^2

Multiply the GCF of the numerical part 2 and the GCF of the variable part xy^2, and you'll get 2xy^2

Help? 11 3/4 is the quotient of a number y and 6 1/4
LUCKY_DIMON [66]

Answer:

y divided by 6 1/4 = 11 3/4

Step-by-step explanation:

First, change the mixed numbers into improper fractions:

y divided by 25/4 = 47/4

Next, multiply both sides by 25/4:

y divided by 25/4 x 25/4 = 47/4 x 25/4

The 25/4's on the left side of the equation cancel each other out, leaving you with:

y = 47/4 x 25/4

Multiply 47 x 25 and keep the same denominator:

y = 1,175/4

Divide and:

y = 293 3/4

The following section is a statement from the rental agreement Tim signed when he rented his car this past weekend. "Upon checko
Firdavs [7]
To check how much Tim will pay to refill the gas tank using one of the on-site pumps, we can create a linear model. We know from our problem that the Renter's charge $4.50 per gallon plus a $5.00 refueling, so let x be the number of gallons and y the total cost.
y=4.50x+5 
We also know that the fuel tank in the car is half empty and t<span>he car has a 12-gallon fuel tank, so half tank is 6 gallons. Lets replace the number of gallons in our linear model with 6 to fin the total cost: 
</span>y=4.50x+5 
y=4.50(6)+5
y=27+5
y=32

Now, to find how much Tim will pay if he decides to refuel the car on his own, we can also create a linear model.
Let x be the number of gallons and y the total cost. We know form our problem that <span>refueling the car on his own will cost $2.59 per gallon and the late fee charge is $32.
</span>y=2.59x+32
<span>We already know that half tank is 6 gallons, so 
</span>y=2.59(6)+32
y=15.54+32
y=47.54
<span>
Comparing the result of our two linear models we can conclude that the correct answer is: </span><span>b. It would be cheaper to return the car on time and pay the refueling costs.</span>

-5 = b -2/3<br><br> b= __<br><br> Please help!
Inga [223]

Answer:

b = -4\frac{1}{3}

or

b = -\frac{13}{3}

Step-by-step explanation:

-5 = b - \frac{2}{3}

Add \frac{2}{3} to both sides of the equation to get rid of the "- \frac{2}{3}" on the right side.

-5 + \frac{2}{3} = b - \frac{2}{3} + \frac{2}{3}

Simplify

-4\frac{1}{3} = b

b = -4\frac{1}{3}

or

b = -\frac{13}{3}
