=============================================
Work Shown:
(g-h)(x) = g(x) - h(x)
(g-h)(x) = (2x-4) - (x+2)
(g-h)(x) = 2x-4 - x - 2
(g-h)(x) = x - 6
(g-h)(-4) = -4 - 6
(g-h)(-4) = -10
--------------------
An alternative method:
g(x) = 2x-4
g(-4) = 2(-4)-4
g(-4) = -8-4
g(-4) = -12
h(x) = x+2
h(-4) = -4+2
h(-4) = -2
(g-h)(-4) = g(-4) - h(-4)
(g-h)(-4) = -12 - (-2)
(g-h)(-4) = -12 + 2
(g-h)(-4) = -10
t-1 4/9+4 5/9=3 2/9. What is t equal to?
I NEED HELPPPP
Answer:
Step-by-step explanation:
As given t-1 4/9+4 5/9=3 2/9
t-13/9+41/9=29/9
t=29/9-41/9+13/9
now taking L.C.M
t=(29+13-41)/9
t=(42-41)/9
t=1/9

0.2385 mL =
L
Answer:
Step-by-step explanation:
1). ∵ 1 L = 1000 ml
∴ 4 L = 4000 ml
2). ∵ 1 cm = 10 mm
∴ 5 cm = 50 mm
3). ∵ 1 mg = 0.1 cg
∴ 5 mg = 0.5 cg
4). ∵ 1 ml = 0.001 L
∴ 25 ml = 0.025 L
5). ∵ 1 gm = 1000 mg
∴ 0.125 gm = 25 mg
6). ∵ 1 ml = 0.001 L
∴ 570 ml = 0.57 L
7). ∵ 1 mm = 0.1 cm
∴ 135 mm = 13.5 cm
8). ∵ 1 mg = 0.001 g
∴ 1820 mg = 1.82 g
9). ∵ 1 g = 100 cg
∴ 0.5 g = 50 cg
10). ∵ 1 ml = 0.001 L
∴ 0.2385 ml = 0.0002385 L

Step-by-step explanation:
If angle 1 is 121 degrees, then angle 7 is 59 degrees. (same side exterior angles)
If angle 8 is 103 degrees, then angle 4 equals 103 degrees (corresponding angles) and angle 3 is 77 degrees. (to angle 4 supplementary angles)
If angle 5 is 116 degrees, then angle 3 is 64 degrees. (same side interior angles)

Use the Commutative Property to write an expression equivalent to -5d + 6
Answer:
6 - 5d is an expression equivalent to -5d + 6 using the commutative Property of Addition.
Step-by-step explanation:
Commutative Property of Addition
We know that we can add two numbers in any order.
For example,
Let 'a' and 'b' be two numbers.
We can add 'a' and 'b' numbers in any order, such as
a + b = b + a
Thus,
a + b = b + a is represented using the commutative Property of Addition.
In our case,
-5d + 6 can be written or represented using the commutative Property of Addition, such as
-5d + 6 = 6 - 5d
It is clear that -5d + 6 can be written in any order such as 6 - 5d.
In other words, 6 - 5d is an expression equivalent to -5d + 6 using the commutative Property of Addition.
Therefore, 6 - 5d is an expression equivalent to -5d + 6 using the commutative Property of Addition.
5.Sally drives 290 miles in
4 and a half hours
What is her average speed :
Answer:
64.4 mph
Step-by-step explanation:
Speed is distance traveled over time.
Distance = 290 miles
Time = 4.5 hours
290/4.5 = 64.4
Answer:
64.44mph
Step-by-step explanation:
If Sally drives 290 miles in 4.5 hours, then how many can she drive in one hour?
speed=distance/time
290/4.5=64.44
Sally drives at an average speed of 64.44 miles per hour.

184500 $ are to be divided between 2 people. One person has 80% of what the other person has. How much does each one receive in $?
Given:
$184500 are to be divided between 2 people.
One person has 80% of what the other person has.
To find:
The amount each one receive in $.
Solution:
Let $x be the amount received by first person. Then,
Amount received by the second person = 80% of x
= 0.80x
Total amount = Amount received by first person + by second person
=[tex]x+0.80x[/tex]
=[tex]1.80x[/tex]
Total amount is 184500. So,
[tex]1.80x=184500[/tex]
[tex]x=\dfrac{184500}{1.80}[/tex]
[tex]x=102500[/tex]
So, the amount received by the first person is $102,500.
[tex]0.80x=0.80\times 102500[/tex]
[tex]0.80x=82000[/tex]
So, the amount received by the second person is $82,000.

Julio went to the bank and took out loan of $2,000 in a simple interest account for 3 years with an interest rate of 2.5%. At the end of 3 years, what is the total amount of money that Julio will have in his account?
Answer: $2,150
Step-by-step explanation:
The amount taken was $2,000
The interest rate was 2.5%
Period is 3 years.
The formula for simple interest is:
= Amount * ( 1 + rate * time)
= 2,000 * ( 1 + 2.5% * 3)
= $2,150

Step-by-step explanation:
solve each equation 7:x=2:3
7 : x = 2 : 3
- divide 7 by 2.
7/2 = 3.5
- this is the scale factor.
- now multiply this by 3.
3 X 3.5 = 10.5
so, x = 10.5

Write an equivalent expression with 3 terms for the expression below.
(-4y - 16) - 8y + 10 + 2y
Answer:
[tex]\left(-4y\:-\:16\right)\:-\:8y\:+\:10\:+\:2y=-10y-16+10[/tex]
Step-by-step explanation:
Given the expression
[tex]\left(-4y\:-\:16\right)\:-\:8y\:+\:10\:+\:2y[/tex]
Remove the parentheses
[tex]=-4y-16-8y+10+2y[/tex]
Group like terms
[tex]=-4y-8y+2y-16+10[/tex]
simplifying
[tex]=-10y-16+10[/tex]
Therefore, the equivalent expression with 3 terms for the expression is:
[tex]\left(-4y\:-\:16\right)\:-\:8y\:+\:10\:+\:2y=-10y-16+10[/tex]
