Answer:
x=-8
Step-by-step explanation:
First you should add 5x+67 and 5x+61 together which is 10x+128
Then you set that equal to 3x+72 which would be: 10x+128=3x+72
After that subtract 3x from both sides which leaves you with: 7x+128=72
Then subtract 128 from 72 which gives you: 7x=-56
Then divide by 7 which gives you x equals negative eight

Line CD is the perpendicular bisector of segment AB. The lines intersect
at point E. Which of these statements is true?
(Hint: it may help to draw a picture, but you don't have to turn it in!)
There is not enough information to be sure.
O E is closer to A than to B.
O E is closer to B than to A.
O E is the same distance from A and B.
plz help me understand this
Answer:
E is the same distance from A and B. ⇒ D
Step-by-step explanation:
Let us explain the meaning of perpendicular bisector
If line m is the perpendicular bisector of line n, then
line m intersect line n at the mid-point of line nThey form 4 right angles around this mid-point∵ Line CD is the perpendicular bisector of segment AB
∴ Line CD intersects segment AB at the mid-point of AB
∵ Line CD and segment AB intersected at point E
→ That means E ∈ CD and E ∈ AB
∴ Point E is the mid-point of line AB
∴ Point E divides line AB into 2 equal parts
→ That means point E is at the same distance from points A and B
∴ E is the same distance from A and B.
The answer is a plane

Maria cut 3/4 yard of ribbon into pieces that are 1/8 yard long. How many pieces of ribbon did Maria cut? don't be a b.*.t.c.h. and not solve it
===============================================
Explanation:
3/4 = 6/8 after multiplying top and bottom of the fraction by 2
She has 6/8 of a yard of ribbon.
If she cuts the ribbon into pieces of 1/8 of a yard each, then she has 6 pieces overall
We can see this if we solve the equation (1/8)x = 6/8. Multiply both sides by 8 to get x = 6.
The number of pieces of ribbon that Maria cut is 6 pieces.
Given,
Maria cut 3/4 yards of ribbon into pieces that are 1/8 yard long.
We need to find how many pieces of ribbon Maria cut.
How do we divide two fractions?We multiply one fraction with the reciprocal of the other fraction.
Example:
a/b ÷ c/d
= a/b x d/c
= ad/bc
We have,
The total length of the ribbon = 3/4 yards
The length of each piece cut from the ribbon = 1/8 yards.
The number of pieces that can be cut:
= 3/4 ÷ 1/8
= 3/4 x 8/1
= 3x8 / 4x1
= 24 / 4
= 6
Thus the number of pieces of ribbon that Maria cut is 6 pieces.

In ΔRST, the measure of ∠T=90°, the measure of ∠S=75°, and ST = 97 feet. Find the length of TR to the nearest tenth of a foot.
9514 1404 393
Answer:
TR = 362.0 ft
Step-by-step explanation:
The tangent relation is useful for this.
Tan = Opposite/Adjacent
tan(75°) = TR/ST = TR/(97 ft)
TR = (97 ft)(tan(75°))
TR ≈ 362.0 ft

Step-by-step explanation:
is the equation y=1/5x+2 is changed to y=1/5x-4, how will graph the line change
Answer:
The answer to this problem is:
It will shift down 6 units
Step-by-step explanation:
not only have the y-intercept(s) change but also where they are positioned, this is shown in the graphs below.
The graph of the line will shift down by 6 units when the equation y = 1/5x + 2 is changed to y = 1/5x - 4 (option b).
To compare the two equations, y = (1/5)x + 2 and y = (1/5)x - 4, we can focus on their y-intercepts. The y-intercept of the first equation is 2, and the y-intercept of the second equation is -4.
When the y-intercept changes from 2 to -4, the graph will shift vertically. The y-coordinate is decreasing from 2 to -4, which means the graph will shift down by 6 units.
Therefore, the correct answer is:
B) It will shift down 6 units.

-18 = 10 + x → Change the x and 10, changing their sign to the opposite:
-x = 10 + 18 → Sum:
-x = 28 → Change the position of the minus sign:
x = -28

HELP!!! Last month, there were 4 sunny days for every rainy day. If there were 30 days in the month, how many days were rainy? Explain your reasoning. If you get stuck, consider using a tape diagram.
Answer:
6
Step-by-step explanation:
Based on the ratio of sunny days to rainy days last month, there would have been 6 rainy days.
For every 4 sunny days, there is 1 rainy day. This means that every 5 days, one of those days will be rainy and 4 will be sunny.
We can therefore represent that as:
= 1/5 of any number of days will be rainy
If there are 30 days therefore, 1/5 of those 30 days will be rainy:
= 1/5 x 30
= 6 days
In conclusion, 6 days will be rainy out of 30 days.

The pH level of a substance can be determined by the formula pH = –log[H+], where [H+] is the hydrogen ion concentration in moles per liter. An alkaline substance has a pH level between 7 and 14. Which ion concentration corresponds to an alkaline substance?
3.5 x 10^-16
5.0 x 10^-12
1.0 x 10^-7
1.1 x 10^-4
Please answer asap
Answer:
B. 5.0 × 10⁻¹² moles per liter.
Step-by-step explanation:
In this exercise we have to calculate the pH levels associated with respective hydrogen ion concentration based on the following formula:
[tex]pH=-\log [H^{+}][/tex]
Where [tex][H^{+}][/tex] is the hydrogen ion concentration, measured in moles per liter.
a) 3.5 × 10⁻¹⁶ moles per liter:
[tex]pH=-\log [3.5\times 10^{-16}][/tex]
[tex]pH \approx 15.456[/tex]
The substance is above the upper bound for alkaline substances.
b) 5.0 × 10⁻¹² moles per liter:
[tex]pH=-\log [5.0\times 10^{-12}][/tex]
[tex]pH \approx 11.301[/tex]
The substance is alkaline.
c) 1.0 × 10⁻⁷ moles per liter:
[tex]pH=-\log [1.0\times 10^{-7}][/tex]
[tex]pH= 7[/tex]
The substance is not acid nor alkaline.
d) 1.1 × 10⁻⁴ moles per liter:
[tex]pH=-\log [1.1\times 10^{-4}][/tex]
[tex]pH \approx 3.959[/tex]
The substance is acid.
Thus, we concluded that correct answer is B.

Fernando evaluated the expression below. StartFraction 5 (9 minus 5) over 2 EndFraction + (negative 2) (negative 5) + (negative 3) squared = StartFraction 5 (4) over 2 EndFraction minus 10 + 9 = StartFraction 20 over 2 EndFraction minus 10 + 9 = 10 minus 10 + 9 = 9. What was Fernando's error?
Answer:
Fernando incorrectly found the product of –2 and –5.
Step-by-step explanation:
Fernando evaluated the numerator of the fraction incorrectly.
Fernando simplified StartFraction 20 over 2 EndFraction incorrectly.
Fernando incorrectly found the product of –2 and –5.
Fernando evaluated (negative 3) squared incorrectly.
Fernando's calculation
5(9-5) / 2 + (-2)(-5) + (-3)^2
= 5(4) / 2 - 10 + 9
= 20/2 - 10 + 9
= 10 - 10 + 9
= 9
Correct calculation
5(9-5) / 2 + (-2)(-5) + (-3)^2
= 5(4) / 2 + (10) + 9
= 20/2 + 10 + 9
= 10 + 10 + 9
= 29
Therefore,
Fernando's error was multiplying (-2)(-5) to be equal to -10 instead of 10
Fernando incorrectly found the product of –2 and –5.
