Answer:

The value of 5x+2y-6 is 20

Step-by-step explanation:

The problem is substitution into equation.

x and y are called unknown variables

Since we have been given values of x and y, we replace them with the values given to solve the expression.

5x means 5 times x

2y means 2 times y

Step 1. Substitute the given values of x and y

When x = 4 and y = 3

5x+2y-6 = 5(4) + 2(3) - 6 = 20 + 6 - 6

= 26 - 6 = 20

Twenty-four students took a test. Fourteen students earned an A and 10 students earned a

horrorfan [7]

Total number of students who did a test was 24
Number of students who scored an A is 14
Number of students who scored a B is 10
Probability that when we randomly select a student, he/she will have an A is:
(Number of students that scored A)/(Total number of students)
=14/24
=7/12
Therefore our answer is 7/12

Evaluate cos0 if sin0= sqrt(5)/3<br><br> a. 9/5<br> b. 2/3<br> c. 5/9<br> d. 3/2

Evgesh-ka [11]

Solution given:

$\sin( \alpha ) = \frac{\sqrt{5} }{3}$

so

P=√5

h=3

b= $\sqrt{3 {}^{2} - \sqrt{5} {}^{2} }$

b=2

so

$\cos( \alpha ) = \frac{b}{h} = \frac{2}{3}$

Note

$\alpha = 0$

<u>b</u><u>:</u><u>⅔</u>

Write a compound interest function to model each situation. Then find the balance after the given number of years.

andriy [413]

Answer:

See explanation

Step-by-step explanation:

The standard compound interest formula is $A = P(1+\frac{r}{n})^{nt}$ where:

P is the principal amount

r is the interest rate (typically as a percentage)

t is the time

n is the times compounded per unit of time

So,

1) $A = 50000(1+\frac{0.03}{12})^{(12)(6)} =59847.42$

2) $A = 43000(1+\frac{0.05}{1})^{(1)(3)} =49777.88$

3) $A = 65000(1+\frac{0.06}{4})^{(4)(12)} =132826.08$

You should check my answers though, I may have mixed up some terms.

Solve the system of inequalities<br> 1-12y<:3y+1; 2-6y>4+4y

ICE Princess25 [194]

For 1 - 12y < 3y+1; y > 15

For 2 - 6y > 4 + 4y; y < -0.2

The given inequalities are:

1 - 12y < 3y + 1

2 - 6y > 4 + 4y

For 1 - 12y < 3y + 1:

1 - 12y < 3y + 1

Collect like terms

-12y - 3y < 1 - 1

-15y < 0

Multiply both sides by -1

-1(-15y) > 0(-y)

15y > 0

Divide both sides by 15

y > 0/15

y > 15

For 2 - 6y > 4 + 4y

Collect like terms

-6y - 4y > 4 - 2

-10y > 2

Multiply both sides by -1

-1(-10y) < 2(-1)

10y < -2

y < -2/10

y < -0.2
