Add the numbers 7 + 10
17 - 7j = -10 - 4j
subtract 17 from both sides
-7j = -27 - 4j
add 4j to both sides
-3j = -27
divide both sides by -3
j = 9

First start with subtracting ten on each side and subtracting 7 on each side, then add 4j to the -7j to get 3j/3 = -27/3 which equals j=9 ; answer is j=9

Maria has baked a cake for Cathy's birthday. The dimensions of the cake are 13 1/2 inches by 6 3/4 inches. The cake is going to
ycow [4]

Answer:

Step-by-step explanation:

Given:

Length = 27/4 in

Width = 27/2 in

5.55% of the cake = 5.55/100

= 1/18 

Therefore, 18 equal squares of cake where 1 piece is 5.55 % of the cake

Since, the cake is twice as long as it is wide, so that means cut half the cake (27/4 × 27/4) into 9 pieces.

Therefore, each has a side of 1/3 * 27/4

= 9/4 inches.

Angle A and angle B are complementary angles. If m∡a = 4x and m∡b = 3x +13, what is the measure of the smaller angle?
bagirrra123 [75]

Answer:

Step-by-step explanation:

Complementary angles mean two two angles sum with equal 90 degrees. Therefore you would need to create an equation to solve for the value of x.

4x+3x+13=90

-13 -13

7x=77

/7 /7

X=11

Now plug in the value of x.

A=4(11) B=3(11)+13

A=44. B=33+13

B=46

Angle a is the smaller angle and measures at 44°

Solve the inequality 7(x + 4) &gt; 0.<br><br> x &lt; -4<br> x &gt; -4<br> x &lt; 4<br> x &gt; 4
spayn [35]
7(x+4)>0

Distribute 7. (multiply by x and 4)

7x+28>0

Subtract 28 on both sides.

7x>-28

Divide by 7 into both sides.

x>-4

x>-4 is the answer. 

I hope this helps!

Use the explicit formula an = a1 + (n – 1) • d to find the 250th term of the sequence below.
solmaris [256]
For this case we have the following equation:
 an = a1 + (n - 1) • d
 Where,
 a1 = 57
 d = 66-57 = 9
 For the term number 250 we have:
 n = 250
 Substituting the values:
 a250 = 57 + (250 - 1) * 9
 a250 = 2298
 Answer:
 
D.2298
