Jose found 14 shells in the beach. He lost the same amount as he has left. Write the doubles addition fact Jose can use to find the number of shells Jose has left.
Answer:
7
Step-by-step explanation:
Number of shells found = 14
Number of shells lost equals number of shells left :
Let Number of shells lost = x
Using the relation:
Number of shells lost = Number of shells left
x =number of shells found - number of shells lost
x = 14 - x
x + x = 14
2x = 14
x = 14 / 2
x = 7
Number of shells left = 14 - x = 14 - 7 = 7

Ariel invests $3,000 in an account that pays him 5% interest, compounded annually. How much money will Ariel have in the account after 3 years if no withdrawals or additional deposits are made?
Answer:
5,120
Step-by-step explanation:
After 3 years, Ariel will have $3,472.88 in the account if no withdrawals or additional deposits are made.
How to calculate compound interest?The formula for compound interest is given:
[tex]A = P(1 +\dfrac{ r}{n})^{(nt)}[/tex]
Where:
A = the final amount,
P = the principal amount,
r = the annual interest rate (as a decimal),
n = the number of times the interest is compounded per year,
t = the number of years,
In this case, we have:
P = $3,000
r = 0.05
n = 1 (compounded annually)
t = 3
Plugging in these values, we get:
[tex]A = $3,000(1 + \dfrac{0.05}{1})^{(1\times 3)[/tex]
A = $3,000(1.05)^3
A = $3,000(1.157625)
A = $3,472.88
Therefore, after 3 years, Ariel will have $3,472.88 in the account if no withdrawals or additional deposits are made.

4. A rectangle with area 1,600 m2 is 4 times as long as it is wide. What is the sum of the diagonals?
We need to write out algebraic equations to describe the information we have, then solve them using substitution.
We will define length as a and width as b.
we know that a x b = 1600 cm3 (area = length x width)
and a=4b
So, we can substitute the vaule 4b for a in the first equation:
4b x b = 1600
we can simplify to 4b2 = 1600
divide both sides by 4:
b2 = 400
take the square root of each side:
b = √400
b=20
So we know the width = 20
length = 4 x width = 80

The amount for NET PAY for this pay period was $
Answer:
240.62$
Step-by-step explanation:
$9.75 per hour
30 hours
Total earned: 292.5$
Federal income tax (withholding) at 10% --> 29.5$
Social Security tax at 6.2% --> 18.14$
Medicare tax at 1.45% --> 4.24$
292.5 - all taxes = 240.62$
Draw lines to match each equation on the left to its number of solutions on the right.
Answer:
1) The equation [tex]2(4x-1)=-8x-2[/tex] has one solution
2) The equation [tex]2(4x-1)=8x-2[/tex] has infinitely many solutions
3) The equation [tex]-2(4x-1)=-8x-2[/tex] has no solution.
Step-by-step explanation:
We need to solve the equation and match with its solution.
1) [tex]2(4x-1)=-8x-2[/tex]
Solving and finding value of x:
[tex]2(4x-1)=-8x-2\\8x-2=-8x-2\\8x+8x=-2+2\\16x=0\\x=0[/tex]
So, We get x =0
So, the equation [tex]2(4x-1)=-8x-2[/tex] has one solution
2) [tex]2(4x-1)=8x-2[/tex]
Solving the equation and finding value of x:
[tex]2(4x-1)=8x-2\\8x-2=8x-2\\8x-8x=-2+2\\0=0[/tex]
So, We get 0 =0
So, the equation [tex]2(4x-1)=8x-2[/tex] has infinitely many solutions
3) [tex]-2(4x-1)=-8x-2[/tex]
Solving the equation and finding value of x
[tex]-2(4x-1)=-8x-1\\-8x+2=-8x-2\\-8x+8x=-2-2\\0\neq -4[/tex]
So, we get 0 ≠ -4
So, the equation [tex]-2(4x-1)=-8x-2[/tex] has no solution.

12 = 6 (8) + b
Enter your math answer
Answer:
B=-36
Step-by-step explanation:
First, do 6(8), which equals 48
The you subtract 48 from both sides, which leaves you with:
-36=B
Answer:
b is equal to negative thirty-six.
Step-by-step explanation:
You can solve this by first multiplying the six and the eight. Eight times six is equal to forty-eight. You can then subtract that forty-eight from both sides, leaving you with the expression b = -36:
[tex]12 = 6(8) + b\\12 = 48 + b\\12 -48 = 48 + b - 48\\-36 = b\\b = -36[/tex]

Answer:
29) x = 12
30) x = 6
31) x = -4
32) x = 5
Not sure if the degree symbol is needed for the answer.
Step-by-step explanation:
Apply angle sum of triangles to all 4 questions.
29) (3x + 4) + 50 + 90 = 180 i.e. x = 12
30) (8x + 7) + 35 + 90 = 180 i.e. x = 6
31) 64 + 65 + (x + 55) = 180 i.e. x = -4
32) 70 + 35 + (14x + 5) = 180 i.e. x = 5
Rick is planting a garden in the shape of a semi-circle. He wants to pour top soil over the garden. Approximately how many square feet does he need to cover in soil?
Answer:
The equation of a line in the slope intercept form is expressed as
y = mx + c
Where
m represents slope
c represents y intercept
The formula for determining slope is expressed as
Slope, m = (y2 - y1)/(x2 - x1)
From the points given,
x1 = 0, y1 = 4
x2 = 2, y2 = 10
Slope, m = (10 - 4)/(2 - 0) = 6/2
Slope = 3
We would determine the y intercept, c by substituting m = 3, x = 0 and y = 4 into the slope intercept equation. It becomes
4 = 3 * 0 + c
c = 4
Thus, the equation of the line would be
y = 3x + 4

Answer: e = -2
Step-by-step explanation:
first, i removed the parentheses.
6 + 0.75e = 2 - 1.25e
then, i moved the terms.
0.75 e + 1.25e = 2 - 6
next, i collected the like terms and calculated them.
2e = -4
finally, i divided both sides.

Terms/CoefficientsSolving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define Systems
3x + 4y = -22
7x + y = 7
Step 2: Rewrite Systems
7x + y = 7
Subtract 7x on both sides: y = 7 - 7xStep 3: Redefine Systems
3x + 4y = -22
y = 7 - 7x
Step 4: Solve for x
Substitution
Substitute in y: 3x + 4(7 - 7x) = -22Distribute 4: 3x + 28 - 28x = -22Combine like terms: -25x + 28 = -22Subtract 28 on both sides: -25x = -50Divide -25 on both sides: x = 2Step 5: Solve for y
Define equation: 7x + y = 7Substitute in x: 7(2) + y = 7Multiply: 14 + y = 7Subtract 14 on both sides: y = -7Graph the following inequalities: a. × + y > 4 b. y + 5× ≤ 4
