Answer:
4x+4x+7x=180
15x=180
x=12
Step-by-step explanation:
Answer:
From the lines we know that that two sides are the same so the other angle is also 4x
the total of a triangle equals 180 so
4x+4x+7x=180
15x=180
x=12

Which polynomial is factored completely?
Completely factored:
(4x+4)(x+1) and 2x(x²-4)
Step-by-step explanation:
We have to check each option one by one, It is sum of two perfect square, As we know sum of two perfect square can't be factored. It is prime equation.
Here we have two factor (4x+4) and (x+1). In both factor degree of x is 1. It is complete factor form. Here we have two factor 4x and x²-4. For second factor it is further factor. Because it is difference of square. Factor of x²-4 = (x+2)(x-2)
Complete Factor: 2x(x+2)(x-2)[/tex],
Here variable are not same. So, it can't be factor (false)

What should be the first step in adding these equations to eliminate y?
8x + 3y = 2
+ 4x - 6y= -7
O A. Multiply the top equation by 4.
O B. Multiply the bottom equation by 8.
C. Multiply the bottom equation by 2.
D. Multiply the top equation by 2.
D. Multiply the top equation by 2.
Answer:
D
Step-by-step explanation:
Given the 2 equations
8x + 3y = 2 → (1)
4x - 6y = - 7 → (2)
Multiplying the top equation (1) by 2 and adding to (2) will eliminate y
16x + 6y = 4 → (3)
Add (2) and (3) term by term to eliminate y
20x + 0 = - 3
20x = - 3 ( y has been eliminated )
A 16-ounce package of cereal costs $4.00. What is the unit cost?
Answer:
$0.25/1oz
Step-by-step explanation:
$4.00 / 16oz = $0.25 per ounce
Answer:
The answer is D) $0.25 for every 1 oz
Step-by-step explanation:
In order to find a unit cost of something, you divide the amount of money per item, by the amount of the product. So, you divide 4/16 and get .25. Then you know already that that is the unit cost. So, every 1 oz of the product costs 25 cents. Hope this helps :)

using the elimination method how do I find x and y for the following problem:
3x+5y=-1
x + 5y = 4
Answer:
x is equal to -3, and y is equal to eight fifths, or 1.6
Step-by-step explanation:
Solving by elimination means to add or subtract one of the equations from the other, eliminating one of their common terms.
Because both of the provided ones have the term 5y (and no other y terms), let's use subtraction:
3x + 5y = -1
- ( x + 5y = 5 )
2x + 0 = -6
Which we can solve pretty quick:
2x = -6
x = -3
We can now solve either of the original equations for y:
x + 5y = 5
-3 + 5y = 5
5y = 8
y = 8/5, or 1.6
To make sure we're correct, let's test our results in the other equation:
3x + 5y = -1
3 × -3 + 5 × 8/5 = -1
-9 + 8 = -1
-1 = -1
So we're good!
What number is 0.409 more than 0.733? HELP

The rain gauge shows 3 centimeters of rainwater.
Which of the equations below gives the height, h, if it rains at a rate of 0.25 centimeters per hour after t hours? Hint: the h is the "y" and the t is replacing "x"
A. h=0.25t+3h is equal to 0 point 2 5 t plus 3
B. h=3t+0.25h is equal to 3 t plus 0 point 2 5
C. t=0.25h+3t is equal to 0 point 2 5 h plus 3
D. t=3h+0.25
Answer:
h=0.25t+3
Step-by-step explanation:
y=mx+b
y=0.25x+3
replace y with h and x with t
h=0.25t+3
Express (x + 10)^2 as a trinomial in standard form.
Answer:
x2-20x+100
Step-by-step explanation:
You have to factor the expression in order to get your answer
Do this by expanding out the expression: (x-10)(x-10) Then factor by multiplying each of the components! Use the FOIL acronym to help you. FOIL stands for First, Outer, Inner, Last. Meaning multiply the first numbers of the expressions together, then the outers, then the inner two numbers, then the last two numbers of the expression.
Multiply x and x to get , multiply x and -10 to get -10x, multiply -10 and x to get -10x, multiply -10 and -10 to get 100. Add them all together: . Then combine like terms
The required trinomial in standard form is x²+20x+100.
Trinomial:Important information:
The expression is the [tex](x+10)^2[/tex].Using the formula [tex](a+b)^2=a^2+2ab+b^2[/tex], we get
[tex](x+10)^2=(x)^2+2(x)(10)+(10)^2[/tex]
[tex](x+10)^2=x^2+20x+100[/tex]
Therefore, the required trinomial in standard form is x²+20x+100.

What is the length of the hypotenuse?
C=

Pythagorean Theorem: a^2 + b^2 = c^2
A and B are the sides given to us, because they're not the hypotenuse. Square each at add them.
That leaves you with 289. Square root it, because we want to find C without being squared.
The square root of 289 is 17, so the hypotenuse is 17 m in length

so SQR or x is 55 degrees
Answer:
x = 55°Step-by-step explanation:
Straight angle equals 180°

Tell whether the rates are equivalent. 0.4 kilometer for every 15 minutes 0.6 kilometer for every 20 minutes
Answer:
no they are not equivalent
Step-by-step explanation:
0.4/15 = 0.026
so for every minute they travel 0.026km
0.6/20 = 0.03
so for every minute they travel 0.03km
so they are not the same/equivalent
