your answer is going to be 100 and how you do that is you're going to estimate which means you're taking an educated guess and is it 70 closer to zero or 100 70 is only 20 numbers away and how you find that is by subtracting 100 from 70 which equals 20 and how you do that to see if it's up or down is 50 is in your middle okay so it's going to go from 0 to 50 to 100 on a number line 70 is in between 50 and 100 so that means that you'll be going up now if you did 30 instead of 70 in your equation rounding by 10 then it would be in between the zero and the 50 which that means that you're going down

Simone applied the distributive property using the greatest common factor to determine the expression that is equivalent to 24 + 56. Her work is shown below.
Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24
Factors of 56: 1, 2, 4, 7, 8, 14, 28, 56
24 + 56 = 8 (4 + 7)
What statement best describes Simone’s error?
Simone did not use the correct factors for 24 in the equation.
Simone did not use the correct factors for 56 in the equation.
Simone did not use the greatest common factor in the equation.
Simone did not use the correct operations in the equation.

The sides of a rectangle are in the ratio of 5:6. If its longer side is 7.2 in., find the shorter side, the perimeter, and the area of this rectangle. PLSSS HELP
Answer:
43.2
26.4
6
Step-by-step explanation:
so first if we know that the loger side's ratio is 6 we divided by 7.2
7.2 divided by 6 which is 1.2
so we mulitply the 5 by 1.2
so the shorter side is 6
6 x 7.2 = 43.2 is the area
14.4 + 12 = 26.4 is the perimeter

2a+4=3 what is the value of a???????
Hey there!
2a + 4 = 3
ADD 4 to BOTH SIDES
2a + 4 - 4 = 3 - 4
CANCEL out: 4 - 4 because that gives you 1
KEEP: 3 - 4 because it helps solve for the a-value
2a = 3 - 4
3 - 4 = -1
2a = -1
DIVIDE 2 to BOTH SIDES
2a/2 = -1/2
CANCEL out: 2/2 because it gives you 1
KEEP: -1/2 because it gives you the value of the a-value
a = -1/2
SIMPLIFY IT!
Therefore, your answer is: a = -1/2
Good luck on your assignment and enjoy your day!

Part A Write an expression to find size of the largest jellyfish. Represent the expression in meters as a product of two numbers in scientific notation.
Answer:
The expression for the size of the largest jellyfish 1 × 108 • 2 × 10-8 meters.
Step-by-step explanation:
A jellyfish can be up to 1 × 108 times bigger than femtoplankton. Find the size of the largest jellyfish by multiplying the size of a femtoplankton by 1 × 108 times.
The size of a femtoplankton is 2 × 10-8 meter. That means the expression for the size of the largest jellyfish 1 × 108 • 2 × 10-8 meters.

1) Given A = {1, 2, 3, 4, 5 }; B = {2,4,6,83 2,4,6,8} Find A∩B, A-B
2) Is it true to say that sin ( A+B) = -sinA + sinB
3) prove that ( tan theta - sin theta ) / ( tan theta + sin theta ) = ( sec theta - 1 ) / ( sec theta + 1 )
Answer:
A∩B = 2,4
A-B = 1,3,5
sin (A+B) = sin(A)cos(B)+cos(A)sin(B)
Step-by-step explanation:
A intersects U means the numbers that are coming to both A and U
set a minus set b of the numbers that are not common to B
multiply the numerator and the denominator by csc(x)
NOTE: I substituted x for theta as I don't have theta on my phone
[tex] \frac{ \csc(x) }{ \csc(x)} \frac{ \tan(x) - \sin(x) }{ \tan(x) + \sin(x) } = \frac{ \sec(x) - 1}{ \sec(x) + 1} [/tex]
[tex] \frac {\csc(x)}{\csc(x)} \frac {\frac ({\sin(x)}{\cos(x)}-\sin(x)} {\frac ({\sin(x)}{\cos(x)} + \sin(x)}) [/tex]

If f(x)= x² + 3x –10, then over which of the following intervals is f(x) <0?
Answer:
The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.
Interval Notation: (−∞,∞)
Set-Builder Notation: {x|x∈R}
f(x) is continuous on (−∞,0).
The function is continuous.

An art teacher has 47 1/3 pounds of clay.he wants to give each student in his class 2 1/2 pounds of clay. The teacher estimates that he has enough clay for 9 students. Is this the best estimates explain
Answer:
47 1/3 = 142 / 3 total clay
2 1/2 = 5 / 2 clay required for each student
If we divide total clay by clay per student
(142 / 3) / (5 / 2) = 284 / 15 = 18.9
So he should have enough clay for 18 students
4(x6+5)=2x+10 I'm not sure what the answer is can somebody help???
Answer:
[tex]4(6x + 5) = 2x + 10 \\ 4 \times 6x + 4 \times 5 = 2x + 10 \\ 24x + 20 = 2x + 10 \\ 24x - 2x = 10 - 20 \\ 22x = - 10 \\ x = \frac{ - 10}{22} = \frac{ - 5}{11} \\ thank \: you[/tex]
Answer:
-5 / 11 or -0.455
Step-by-step explanation:
this is a very simple question that does not need much complexity about it
we have
4( 6x + 5 ) = 2x + 10
first of all, we open the bracket;
24x + 20 = 2x + 10
now, we have to collect like terms;
24x - 2x = 10 - 20
22x = -10
divide through by 22 to give us!
22x / 22 = -10 / 22
x = -5 / 11
therefore,
x = - 5 / 11
hope that helps

Find the x and y intercepts
Answer:
x:(-1,0),(5,0)
y:(0,-2)
Answer:
see explanation
Step-by-step explanation:
The x- intercepts are where the graph crosses the x- axis
The graph crosses the x- axis at x = - 1 and x = 5 ← x- intercepts
The y- intercept is where the graph crosses the y- axis
The graph crosses the y- axis at - 2 ← y- intercept

Solve the system by substitution.
−5x+2y=14
y=3x+2
let −5x+2y=14 be [1]
& y=3x+2 be [2]
Finding the value of x
By substituting y in [2] for y in [1]
⇒ −5x + 2(3x+2) = 14 [expand the bracket]
⇒ -5x + 6x + 4 = 14 [subract 4 from both sides and simplify]
⇒ x = 10
Finding the value of y
Since x =10, we can substitute value of x into [2]
⇒ y = 3(10) + 2
⇒ y = 32

Type the integer that makes the following addition sentence true: 9 + what = 2
I believe the answer to be (-7)
Answer:
-7
Step-by-step explanation:
Step 1: Make an equation.
[tex]9 + x = 2[/tex]Step 2: Subtract 9 from both sides.
[tex]9 + x - 9 = 2 - 9[/tex] [tex]x = -7[/tex]Step 3: Check if solution is correct.
[tex]9 + (-7) = 2[/tex] [tex]9 - 7 = 2[/tex] [tex]2 = 2[/tex]Therefore, the integer that makes the addition sentence true is -7.
