You have $80 in your bank account each week plan to deposit $9 from your allowance and $25 from your paycheck. The equation b=80+(25+9)w gives the amount b in your account after w weeks. How many weeks from now will you have $315 in your bank account?

There will be $315 in the account after _weeks.

Answer:

$57.50

Step-by-step explanation:

find 10% of 50 first, which is 5, because 5 × 10 = 50, then add $10 to the $50 beacause 50 × 0.2 = 10, next, remove 5%, to do this divide 10% by 2 to get $2.50, 60 - 2.5 = 57.5

Answer:

x = 0

y = -3

Step-by-step explanation:

-5x + y = -3 --------------(I)

3x - 8y = 24 ------------(II)

Multiply the equation (I) by 8

(I)*8    - 40x + 8y = -24

(II)         3x -  8y   =  24   {Add and y will be eliminated}

           -37x          = 0

                     x     = 0

Plugin x = 0  in equation(I)

-5*0 + y = -3

     0 + y = -3

           y = -3

Answer:

- 5x + y =-3    ......1

3x -8y = 24.........2

eqn 1 is multiply by 8 .we get -40 x +8y=-24 .....3

-40 x +8 y =-24 ...........3

3 x   - 8y  = 24     ......... 2

·································

-37 x +0 = 0

··························

x =0

put x = 0 in equation 2

3 x -8 y =24

3×0 -8 y = 24

0 -8 y=24

-y =24÷8

-y =3

y = -3

ans ;

x = 0

y = -3

Answer:

74.8

Step-by-step explanation:

Cos M = adjacent/hypotenuse = 26/99

M = [tex]Cos^{-1}[/tex](26/99)

M = 74.774 ≅ 74.8

Answer:

hello again

Step-by-step explanation:

the radius of the circle is 6mm

for having the circumference we need diameter

for having diameter we should multiply in 2

so:

[tex]d = 2r \\ \\ d = 2 \times 6 = 12mm \\ v = \pi \: d \\ v = 12\pi \: mm[/tex]

i hope this is the answer

Answer:

The price increased by 64.5, which makes a total of 279.5

Step-by-step explanation:

215*0.30 = 64.5

215 + 64.5 = 279.5

0.30 = 30% of 100

When you multiply by 0.30 you get 30%, or with any decimals, like multiply by 0.50 to get 50% of something, etc.

Answer: d. 5

Step-by-step explanation:

Answer:

A and B are correct

Step-by-step explanation:

if x:y is 1:3 then x is 1 and y is 3

1/3 of 3 is 1 so A is correct

3/4(1+3) is 3 so B is correct

But

1/4 × 3 is not 1 so C is not correct

3/4 ×1 is not 3 so D isn't correct

Answer:

The range here is 85

Step-by-step explanation:

Here, we want to calculate the range of the data

Mathematically, the range is defined as the difference between the lowest value and the highest value in the dataset

From the given data points, the highest value is 189, while the lowest value is 104

So the range is the difference between the two which is;

189-104 = 85

Answer:

The value of x = 3.

Step-by-step explanation:

The ratio between length and width is given by:

[tex]\frac{L}{W}=\frac{5}{3}[/tex]

Where:

Now, we know that each dimension is reduced by x inches, it means:

[tex]L=18-x[/tex]

[tex]W=12-x[/tex]

Then, we will have:

[tex]\frac{18-x}{12-x}=\frac{5}{3}[/tex]

Finally, we just need to solve it for x.  

[tex]3(18-x)=5(12-x)[/tex]

[tex]5x-3x=60-54[/tex]

[tex]2x=6[/tex]

[tex]x=3[/tex]

Therefore, the value of x = 3.

I hope it helps you!

Answer:

A. ST = RU

Step-by-step explanation:

Quadrilaterals are four sided figures. Examples are: square, rectangle, trapezium, parallelogram etc. A parallelogram is a quadrilateral that has equal opposite and parallel sides.

This implies that in the given question since RS || TU, then;

RS = TU = 6

So that for RSTU to be a parallelogram,

ST = RU

Thus, the appropriate option to the question is A.

Answer:

4xy/z^2

Step-by-step explanation:

Here, we want to make a division

We have this as;

24xy^2/6yz^2

that will be

24/6 * x * y^2/y * 1/z^2

= 4 * x * y * 1/z^2 = 4xy/z^2
