Answer:
Incorrectj = -2Explanation:
-2j - 10 = -6
Add 10 To Both Sides−2j − 10 + 10 = −6 + 10
−2j = 4
Divide Both Sides By -2-2j / -2 = 4 / -2
j = -2Tim has completed five math problems and 13 minutes if he continues at the same rate how long will it take him to finish 20 problems
Answer:
52 minutes
Step-by-step explanation:
it takes him 13 minutes to complete 5 so if he wants to do 20 problems do 20 divided by 5 (4) then do 13 times 4=52

Step-by-step explanation:
The floor of a rectangular living room is 12 feet by 16 feet. What is the distance between
opposite corners of the living room?
Answer:
The width of Dana's living room is 16 feet.
Explanation:
Because Dana's living room is rectangular and we are given the length of one side and the length of the diagonal we can use the Pythagorean Theorem to solve this problem.
For a right triangle which the length, width and diagonal make up the Pythagorean Theorem states:
a
2
+
b

=
c

Let the length of 12 be
a
and because the diagonal is the hypotenuse of the triangle (the side opposite the right angle) we let
c

-2(x-4)=4 can x=2 be the solution
Answer:
Step-by-step explanation:
-2x + 8 = 4
-2x = 4 - 8
-2x = - 4
x = - 4/-2 = 2
replace x with 2 on the equation
-4-4=4
so answer is no
-8=4 not possible

Answer:
c. 80
Step-by-step explanation:
cos x = sin(x-70)
cos x = cos [90-(x-70)]
cos x = cos (90-x +70)
cos x = cos 160 -x
x= 160-x
2x = 160
x =80

The figure below shows a right triangle:
What is r ÷ p equal to? (6 points)
Group of answer choices
A. sin y°
B. sin x°
C. tan y°
D. tan x°
Answer:
tan y°
Step-by-step explanation:
by using the Sine Rule (See attached), we can form the equation:
[tex]\frac{r}{sin (y)} = \frac{p}{sin (x)}[/tex]
rearranging this, we get:
[tex]\frac{r}{p} =\frac{sin(y)}{sin(x)}[/tex] ---------------------eq 1
Recall that all internal angles of a triangle must sum to 180°. we observe that we have a right triangle where one of the angles is 90°. It then follows that the sum of the other two angles must sum to 90°
i.e x + y = 90°
with a little rearranging, we get
x = (90° - y)
Substituting this into eq 1 above, we get:
[tex]\frac{r}{p} =\frac{sin(y)}{sin(90- y)}[/tex] ---------eq 2
recall that from the trigonometric co-function identities,
sin (90°- y) = cos y
substituting this into eq 2 gives :
[tex]\frac{r}{p} =\frac{sin(y)}{cos(y)} = tan(y)[/tex] (answer)

Pat volunteered to bake 80 biscuits for a family reunion breakfast. She plans to bake 8 biscuits in each pan. Which number sentence can be used to find p, the number of pans of biscuits that she will need to bake?
Answer: 10 pans
Step-by-step explanation:
Step 1:
If the number of biscuits needed= 80
Step 2:
And the number of biscuits on each pan= 8
Step 3:
Then the number of pans needed= 80 ÷ 8
Answer: 80 ÷ 8 = 10pans
7x + 4 = 25, then x is equal to
a) 29/ 7 b) 100/7 c) 2 d/ 3
Answer:
d) 3
Step-by-step explanation:
7x+4=25
7x=21
X=3
Answer: D. 3
Step-by-step explanation:
Given
7x+4=25
Subtract 4 on both sides
7x+4-4=25-4
7x=21
Divide 7 on both sides
7x/7=21/7
x=3

Can someone simplify it or expand it please I need it in like 5 mins !
Answer:
5x+6
Step-by-step explanation:
x-3+7x+21-3x-12
5x+6
[tex] =\tt x - 3 + 7(x + 3) - 3x - 12[/tex]
[tex] =\tt x - 3 + 7x + 21 - 3x - 12[/tex]
[tex] =\tt 7x + x - 3x - 3 - 12 + 21[/tex]
[tex] =\tt 8x - 3x - 15 + 21[/tex]
