Drag the tiles to the boxes to form correct pairs. Multiply the pairs of numbers and match them to their products. (-7)(-1.2) 5 (-2)—2) -5 (2.5)(-2) 8.4 (7)(-1.2) -8.4
Answers
(-2 1/2)(-2)= 5
(2.5)(-2)= -5
(7)(-1.2) =-8.4
The correct matches are;
1) (-7) (-1.2) = 8.4
2) 5 = (-2 1/2) (-2)
3) -5 = (2.5) (-2)
4) (7) (-1.2) = - 8.4
What is Multiplication?
To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
The expressions are,
a) (-7) (-1.2)
b) 5
c) (-2 1/2) (-2)
d) -5
e) (2.5) (-2)
f) 8.4
g) (7) (-1.2)
h) -8.4
Now, Solve the expressions in simplest form;
a) (-7) (-1.2) = 8.4
b) 5 = 5
c) (-2 1/2) (-2) = -5/2 x - 2 = 5
d) -5 = -5
e) (2.5) (-2) = -5
f) 8.4 = 8.4
g) (7) (-1.2) = - 8.4
h) -8.4 = -8.4
Thus, The correct matches are;
1) (-7) (-1.2) = 8.4
2) 5 = (-2 1/2) (-2)
3) -5 = (2.5) (-2)
4) (7) (-1.2) = - 8.4

4. A store offers packing and mailing services to
customers. If a customer ships a box
weighing 4 pounds, it would cost $15. If a
customer ships a box weighing 8 pounds, it
would cost $23. Identify the following
characteristics:
Answers
Answer/Step-by-step explanation:
In the situation explained in the question, the cost of shipping is dependent on the weight of the box to be shipped.
For a box of 4 pounds, total shopping cost (x) => $15 (y)
For a box of 8 pounds (x), total shopping cost => $23 (y)
Therefore:
a. The input is weight of box
b. The output is cost of shipping
c. Using the 2 given pair (4, 15) and (8, 23), slope is calculate using the formula below:
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{23 - 15}{8 - 4} = \frac{8}{4} = 2 [/tex]
Slope = 2
d. The slope represents the amount charged per pound of weight. That is, $2 per pound.
e. Let's derive an equation to represent the situation using the slope-intercept formula given as y = mx + b
y = total cost of shipping
x = weight of box
m = average cost per pound = slope
b = y-intercept = flat fee charged for shipping before adding the cost of weight per pound
Substitute x = 4, y = 15, m = 2 into y = mx + b, and solve for b
15 = 2(4) + b
15 = 8 + b
15 - 8 = b
7 = b
b = 7
The equation would be y = 2x + 7
The y-intercept = 7
f. The y-intercept, 7, is the starting amount, that is the flat fee charged before the cost per pound of weight of a box is added to give total cost of shipping.

x = a
Answers
Answer:
x=3
Let me know if you need an explanation.
Answer:
x = 3
Step-by-step explanation:
Step 1. add 11 to both sides
3x + 4 = 8x - 11
+11 +11
3x + 15 = 8x
Step 2. subtract 3x from both sides
3x + 15 = 8x
- 3x -3x
15 = 5x
Step 3. divide by 5 to isolate x
15 = 5x
/5 /5
x = 5
A savings account earns 2.7% yearly interest. Which equation shows how many years, t, it will take for the account to double?
Answers
Answer:
1.027t = 2
Step-by-step explanation:
Given that :
Saving account earns 2.7% interest yearly
The number it will take for the account to double
Let
Number of years = t
Interest earned yearly = 2.7% = 0.027
Amount = p(1 + rt)
Where P = principal
R = rate ; t = time in years, A = final amount
If p = 1 ;
For account to double,
Final amount = 2 * principal (p)
final amount = 2 * 1 = 2 ; hence, Final amount = 2
2 = 1(1 + 0.027t)
2 = 1 + 0.027t
2 = 1.027t
A hill on a hiking trail goes up to 69 feet over a distance of 138feet. Find the grade of the hill
Answers
Answer: The grade of the hill = 50%
Step-by-step explanation:
The grade is the slope( expressed as a percent). To evaluate the slope we divide the rise by the run.
Given: A hill on a hiking trail goes up to 69 feet over a distance of 138 feet.
So, rise= 69 feet , run = 138 feet.
The grade of the hill = [tex]\dfrac{rise}{run}\times100[/tex]
[tex]=\dfrac{69}{138}\times100=50\%[/tex]
Hence, the grade of the hill = 50%

LeAnn bought a total of 48 cupcakes. Each cupcake cost $0.55, including tax. Of the cupcakes she bought, 3 8 were chocolate. What was the total cost of only the chocolate cupcakes?
Answers
Answer:
Total cost= $20.9
Step-by-step explanation:
Giving the following information:
Unitary cost= $0.55
Number of chocolate cupcakes= 38
To calculate the total cost of chocolate cupcakes, we need to use the following formula:
Total cost= unitary cost*number of units
Total cost= 0.55*38
Total cost= $20.9
Nora jogs 414 miles on Monday. She jogs 112 fewer miles on Tuesday. Write and evaluate an addition expression to find how many miles Nora jogs on Tuesday.
Answers
Answer:
Let's define the variables:
M = # of miles that Nora jogs on Monday
T = # of miles that Nora Jogs on Tuesday
We know that:
"Nora jogs 414 miles on Monday"
Then we have:
M = 414 mi
"She jogs 112 fewer miles on Tuesday"
This can be written as:
T = M - 112 mi
This is the equation that we need to solve.
Here we can simply replace the value of M by 414mi and get:
T = 414 mi - 112 mi = 302 mi.
Nora jogs 302 miles on Tuesday.

Please answer these questions.It is only two questions and they are super small.I have put the picture of the question down below.
Answers
Answer:
9. y= ¼x -5
10. y= 2x +18
Step-by-step explanation:
Slope-intercept form:
y= mx +c, where m is the slope (also known as gradient) and c is the y-intercept.
9. The given equation is already written in the slope-intercept form. The coefficient of x is ¼, thus the gradient of the given line is ¼.
Parallel lines have the same gradient and hence, gradient of line is also ¼.
Substitute m= ¼ into the equation:
y= ¼x +c
To find the value of c, substitute a pair of coordinates.
When x= 8, y= -3,
-3= ¼(8) +c
-3= 2 +c
c= -3 -2
c= -5
Thus, the equation of the line is y= ¼x -5.
10. Gradient of given line= 2
Parallel lines have the same gradient.
Thus, gradient of line= 2
Substitute m=2 into the equation:
y= 2x +c
When x= -4, y= 10,
10= 2(-4) +c
10= -8 +c
c= 10 +8 (+8 on both sides)
c= 18
Therefore, the equation of the line is y= 2x +18.
