Answer:
z=-3
Step-by-step explanation:
Answer:
z=3
Step-by-step explanation:
42=−7(z−3)
Simplify both sides of the equation.
42=−7(z−3)
42=(−7)(z)+(−7)(−3)(Distribute)
42=−7z+21
Flip the equation.
−7z+21=42
Subtract 21 from both sides.
−7z+21−21=42−21
−7z=21
Divide both sides by -7.
-7z/-7=21/7
z=3

Anyone know how to solve for x and y on this problem?
[tex]\boxed{\boxed{\pink{\bf \dag Value \ of \ x \ is \ 6\ and\ y \ is\ (-21) .}}}[/tex]
Step-by-step explanation:In the Question , its given that ∆ART [tex]\cong[/tex] ∆ DFI . And we need to find the values of x and y . So we know that ,
If two triangles are congruent then their Corresponding angles and sides are equal.Hence here in ∆ ART & ∆ DFI :-
AT = DI ( cpctc)AR = DF ( cpctc)[tex]\bf\implies AT = DI \\\\\bf\implies 6x + 31 = 67 \\\\\bf\implies 6x = 67 - 31 \\\\\bf\implies 6x = 36 \\\\\bf\implies x =\dfrac{36}{6}\\\\\bf\implies \boxed{\red{\bf x = 6}}[/tex]
Hence the value of x is 6 .
[tex]\rule{200}2[/tex]
[tex]\bf\implies AR = DF \\\\\bf\implies -4y+19 = 103\\\\\bf\implies -4y = 103-19 \\\\\bf\implies -4y = 84 \\\\\bf\implies y =\dfrac{84}{-4}\\\\\bf\implies \boxed{\red{\bf y = -21}}[/tex]
Hence the value of x is 6 and y is (-21) .Erica’s parents gave her $500 for her high school graduation. She put the money into a savings account that earned 7.5% annual interest.

(where the longer it takes to solve a problem and the fewer people who answer it correctly, the more difficult it is). On each subsection, question 1 will be "easy" and question 15 will be considered "difficult." However, the ascending difficulty resets from easy to hard on the grid-ins.
Hence, multiple choice questions are arranged in increasing difficulty (questions 1 and 2 will be the easiest, questions 14 and 15 will be the hardest), but the difficulty level resets for the grid-in section (meaning questions 16 and 17 will again be "easy" and questions 19 and 20 will be very difficult).
the answer is 4/.12

angles FMK and HMK are congruent because corresponding angles are congruent---- if you were to cut this in half horizontally, then place the two pieces on top of each other, you would see that the angles line up perfectly.
angles GMK and JNL are supplementary because they add up to 180 degrees-- Alternate exterior angles are supplementary.

How many groups of 3/4 are in each of the following questions?
11/4
Enter answer as a fraction.
Answer:
12 1/3
Step-by-step exp
First, you need to add up 11/4 and
6 1/2
11/ 4 + 6 1/2 = 11/4 + 13/2 = 37 / 4
To find how many 3/4 we have in 37/4, we simply dividw 37/4 by 3/4
37/4 ÷ 3/4
= 37/4 × 4/3 (4 will cancel out 4)
= 37/3
=12 1/3

Given the diagram below, solve for the value of x.
==========================================================
Explanation:
Sides ED and FD are the same length due to the red tickmarks.
The angles opposite these side lengths, angle E and angle F, are congruent as well. So angle F is also x.
For any triangle, the three angles always add to 180
F+E+D = 180
x+x+74 = 180
2x+74 = 180
2x+74-74 = 180-74 .... subtract 74 from both sides
2x = 106
2x/2 = 106/2 ... divide both sides by 2
x = 53
As a check,
F+E+D = x+x+74 = 53+53+74 = 180
which verifies the answer.

4x + 5
2x + 21, smby help me wit dis pls
Answer: x = 8
Step-by-step explanation:
4x + 5 = 2x + 21
4x + 5 - 2x = -2x + 2x +21 (Subtract 2x from both sides)
2x + 5 = 21
2x + 5 - 5 = 21 - 5 (Subtract 5 from both sides)
2x = 16
2x/2 = 16/2 (Divide both sides by 2)
x = 8

Jeffrey is 5 years older than his brother. If j represents Jeffrey’s age, the expression j−5 can be used to find his brother’s age. If Jeffrey is 23, how old is his brother?
If j=23 and j-5 is how old Jeffery's brother is then Jeffrey's brother is 17 years old.
So j=17
