So if 4% was put into the account every year, then you would have to find 4% of 4,000, which is 160. So 160*3=480. 4,000+480= 4,480 dollars. That is how much would be in the account.

Step-by-step explanation:

The number of girls in a mixed school is 420. If the ratio of boys to girls in the school is 3:2, how many students are in the s

shutvik [7]

$\huge{ \bf{ \underline{ \underline{ \pink{Solution:}}}}}$

Let,

Number of boys be 3x
Number of girls be 2x
Then, Total number of students = 3x + 2x = 5x

It is given that,

➙ Number of girls = 420

Then,

➙ 2x = 420

➙ x = 420/2 = 210

No. of boys = 3x = 630

Then,

➙ Number of students = 5x

➙ Number of students = 5(210)

➙ Number of students = 1050

ANSWER - 1050

Use substitution to solve the system of equations Y+x=3 Y=1.5x+1

Serjik [45]

The solution to given system of equation is (x, y) = (0.8, 2.2)

Solution:

Given system of equations are:

y + x = 3 --------- eqn 1

y = 1.5x + 1 ---------- eqn 2

We have to solve the above system of equations by substitution method

Substitute eqn 2 in eqn 1

1.5x + 1 + x = 3

Combine the like terms

2.5x + 1 = 3

Move the constants to Right hand side of equation

2.5x = 3 - 1

2.5x = 2

x = 0.8

Substitute x = 0.8 in eqn 2

y = 1.5(0.8) + 1

y = 1.2 + 1

y = 2.2

Thus the solution to given system of equation is (x, y) = (0.8, 2.2)

Which number is one-half of the way between 2.2 and 8.5?

defon

Let us take 0instead of 2.2 meaning 8.5-2.2=6.3
then we need to find the mid of 6.3=3.15
then we need to add 2.2 to 3.15= 5.35
