Answer:
False your answer will 4x-16
Step-by-step explanation:
you have to distribute 4 to x and 4 to 4. so you will do 4*x=4x and 4*4=16. Now you still have the subtraction sign so your answer will be 4x-16.

Answer:
X = 78, Z = 29, and Y = 102
Step-by-step explanation:
X = 78. 43 + 59 = 102. There has to be 180 degrees in a triangle. So subtract 180 by 102.
Z = 29. Think of the whole triangle for this one. 43 + 49 + 59 = 151. 180 - 151 = 29.
Y = 102. Plug in the value of Z. 49 + 29 = 78. 180 - 78 = 102.

Identify the range of the function shown in the graph.
Answer:
-3 < x < 3
Step-by-step explanation:
c) Jasper and Emma are training for a marathon. Jasper runs 6 kilometers at a
time while Emma prefers to run in blocks of 3 kilometers. At the end of a
month, they realize that they have run same total number of kilometers. What
is the smallest number of kilometers that each must have run?
Answer:
The smallest number of kilometers that each must have ran is 6 km
Step-by-step explanation:
The distance Jasper prefers to run at a time = 6 km
The distance Emma prefers to run at a time = 3 km
The distance ran by Jasper at month end = The distance ran by Emma at the end of the month
The smallest number of kilometers that each must have ran is given by the lowest common multiple, LCM of 6 and 3 as follows;
The multiples of 6 are;
6 × 1 = 6, 6 × 2 = 12...
The multiples of 2 are;
3 × 1 = 3, 3 × 2 = 6...
∴ The LCM of which = 6
Therefore, the smallest number of kilometers that each must have ran = 6 km

Please help I will give brainliest
Answer:
x ≥ -6
Step-by-step explanation:
The arrow is directing towards the right, in which the line contains number greater than -6. Moreover the circle on top of -6 is closed, proving that it is 'greater than or equal to'. (if it was greater than, the circle on top of the number would be open; the inner part of the circle wouldn't be shaded)
The radius of each tire on Carson's dirt bike is 10 inches. The distance from his house to the corner of his street is 157 feet. How many times will the bike tire turn when he rolls his bike from his house to the corner? Use 3.14 to approximate π.
Answer:
30
Step-by-step explanation:
the street and the diameter of the bike are not measured in the same units. We have to convert them to the same units
1 feet = 12 inches
157 x 12 = 1884
circumference of a circle = 2nr
2 x 3.14 x 10 = 62.8 in
Number of revolutions = 1884/62.8 = 30

how do I solve for x for number 4
Answer: 20.8
Step-by-step explanation:
Since it is an equilateral triangle, we know the bottom is also 24. We also know that line E is bisecting the base. So using the smaller right triangle we know that the hypotenuse is 24 and one leg is 12. So use the Pythagorean theorem.
[tex]a^{2} +b^{2} =c^{2} \\12^{2} +b^{2} =24^{2} \\144+b^{2} =576\\b^{2} = 432\\b= 20.8[/tex]

What is the arc measure of minor arc AB on circle P in degrees?
Answer:
AB = 74°
Step-by-step explanation:
Minor arc AB is equal to the measure of the central angle APB , then
∠ APB = 360° - 286° = 74° , thus
minor arc AB = 74°
Arc measure of minor arc AB on circle P = 74 degrees
In the given circle,
Arc measure of major arc = 286 degree
Since we know that,
Measure of complete circle = 360 degree
Therefore,
Angle of minor sector = 360 - 286
= 74 degree
We also know that,
A circle sector is a segment or component of a circle made up of an arc and its two radii. A circle's sector can be compared to the form of a pizza slice. A sector is generated when two circle radii meet at both ends of an arc. An arc is merely a part of the circle's circumference.
Since,
Angle of sector = measure of arc
Hence,
Measure of minor arc = 74 degree.

Nate scored a 990 on his first autempton
the SAT and a 1140 on his second attempt
Percent of change classify as a percent increase or decrease
Answer:
It was a percentage increase of 15.15%
Step-by-step explanation:
1140 is greater than 990, so it is an increase in scores
Percentage increase = (change in score / first score) x 100
change in score = second score - first score
1140 - 990 = 150
(150 / 990) x 100 = 15.15%

Which shows an expression to represent his current amount and the current value of his account if s = 80? StartFraction s Over 2 EndFraction + 100; when s = 80 the latest balance of Ahmed's savings is $140 2 s + 100; when s = 80 the latest balance of Ahmed's savings is $260 s squared + 80; when s = 80 the latest balance of Ahmed's savings is $6,480 s squared + 100; when s = 80 the latest balance of Ahmed's savings is $6,500
Answer:
2s + 100; when s = 80 the latest balance of Ahmed's savings is $260
Step-by-step explanation:
s = amount he originally had in savings
doubled his savings, then deposited another hundred dollars
2s + 100
If s = 80
2s + 100
= 2(80) + 100
= 160 + 100
= 260
2s + 100; when s = 80 the latest balance of Ahmed's savings is $260
