4t+6s=4524
t+s=925

Multiply the second equation by -4 to cancel the variable t
4t+6s=4524
-4t-4s=-3700
2s = 824
Divide both sides by 2
S= 412

925-412= 513
T=513

How do you do this?
ELEN [110]
Use the Pythagorean Theorem: a² + b² = c².

a and b are the legs of the right triangle, and c is the hypotenuse.

2) 5² + b² = 6²
    25 + b² = 36
    b² = 11
    b = 3.3 cm

3) 7² + b² = 8²
    49 + b² = 64
    b² = 15
    b = 3.9 cm

4) a² + 5² = 13²
     a² + 25 = 169
     a² = 144
     a = 12 cm

Find the discriminant for each quadratic function below. Then list the number of zeros/solutions for each quadratic function.
Hunter-Best [27]

Answer:

Step-by-step explanation:

The discriminant is found in

b^2-4ac which is part of the quadratic formula. In

4x^2+10x-16=0, a = 4, b = 10, c = -16. Filling in for the discriminant:

10^2-4(4)(-16)=100+256=356

It's positive so we know we have real roots; it's not a perfect square, so our solutions are 2 complex rational.

In -16x^2-7x+3=0, a = -16, b = -7, c = 3. Filling in for the discriminant:

(-7)^2-4(-16)(3)=49+192=241

It's positive and not a perfect square so the 2 solutions are complex rational

The fifth graders are planning a pizza party. Each fifth grader will eat two slices of pizza with a favorite topping. One-half o
icang [17]
32 students choose a favorite topping for their slices.

Let x be the total number of students.

1/2 of the total students, or 1/2x, choose pepperoni.
1/4 of the total students, or 1/4x, choose extra cheese.
1/8 of the total students, or 1/8x, choose sausage.
4 students choose mushrooms.

We know that together, these equal the total number of students, x:
1/2x+1/4x+1/8x+4=x

We will use 8 as the common denominator:
4/8x+2/8x+1/8x+4=x


Combining like terms:
7/8x+4=x

Subtract 7/8x from both sides:
7/8x+4-7/8x=x-7/8x
4=1x-7/8x
4=1/8x

Divide both sides by 1/8:
4÷(1/8) = 1/8x÷(1/8)
4/1÷(1/8) = x
4/1×8/1 = x
32/1 = x
32 = x
