Work out the point of intersection of the lines
2x + 3y = 11 and 2y = 13 – 3x

Answer:

m<E=22

Step-by-step explanation:

m<B and m<D are congruent therefore, m<D=68

m<C and m<E are congruent.

All interior angles if a rhombus adds up to 180 degrees.

So... 68+68=136

Subtract the 136 from 180

180-136=44

Because m<C and m<E are congruent divide 44 by two

44/2= 22

m<C and m<E equal 22

Answer:

y = |x| is a parent function

y = |x| - 7 is a translation of the parent function vertically by 7 points down

The shape is same, just the entire graph has shifted down.

It's translated edition of parent function y=|x|

If we translate it 7units down then the function is

So

Everything is same

Just the graph shifted 7units downwards

C. 9 square roots of 2

To answer this question, it's super important that you understand the ratio of sides for special triangles. This triangle in particular, a 45-45-90 triangle, has a ratio between the legs and hypotenuse of 1:1:

Since we are given the value of the hypotenuse, we know that the value of the two sides multiplied by [tex]\sqrt{2}[/tex] will be 18. Knowing this, we can write out an equation:

u*[tex]\sqrt{2}[/tex] = 18

u = [tex]\frac{18}{\sqrt{2} }[/tex]

Multiply both sides by [tex]\sqrt{2}[/tex] in order to get rid of the root in the denominator:

u = [tex]\frac{18*\sqrt{2}}{\sqrt{2} * \sqrt{2}}[/tex]

u = [tex]\frac{18*\sqrt{2} }{2}[/tex]

u = 9[tex]\sqrt{2}[/tex]

Answer:

40.35

Step-by-step explanation:

to find the amount without tax:

97 x .6 (60%) = 58.2 (the amount that will be taken off)

so 97 - 58.2 = 38.8 (the amount the pole will be WITHOUT tax)

to find the tax:

38.8 (sale price) x .04 (4 percent) = 1.552, rounded 1.55

to find full price:

38.8 (sale price) + 1.552 or 1.55 (tax) = 45.352 or 40.35

Answer:

Below in bold.

Step-by-step explanation:

cos x = adjacent side / hypotenuse

= 8/21

= 0.380952

So m < x =  arccos 0.380952

= 67.607

= 68 degrees to nearest degree.

Answer:

w = -12

Step-by-step explanation:

You basically have 90% of the question done. You just needed to divide -60 by 5 and then get -12.

Good Luck!!!!!

=====================================================

Explanation:

You're on the right track. You start off subtracting 35 from both sides, and then next divide both sides by 5. Your steps are 100% correct. The last thing to do is to simplify each side after what you wrote. The -60/5 on the left simplifies to -12, while the 5w/5 on the right simplifies to w. We end up with -12 = w and that's the same as w = -12.

--------------

To verify, replace every copy of 'w' with -12 in the original equation and simplify each side.

-25 = 35 + 5w

-25 = 35 + 5(-12)

-25 = 35 - 60

-25 = -25

We end up with the same thing on both sides, so the answer is confirmed.

Answer:

x = 66

Step-by-step explanation:

All triangle angles add up to 180 so:

x + 79 + 35 = 180

x + 114 = 180

x = 180 - 114

x = 66

Answer:

66°

Step-by-step explanation:

Since the sum off all the angles of a triangle is 180°,

x + 79° + 35° = 180°

x + 114° = 180°

x = 180° - 114° = 66°

Therefore, x = 66°

Step-by-step explanation:

Let the number of girls in the class be 3. Then the number of girls who study German is , as is

the number of boys who study German. So the number of girls who study French is 2 and the

number of boys who study French is 2 × 2 = 4.

Therefore the total number of boys and girls in the class is + + 2 + 4 = 8 and hence is a

multiple of 8. Of the options, only 32 is divisible by 8.

Answer:

A

Step-by-step explanation:

a positive number times a negative number is equal to a negative number.

Because all negative numbers have a value less than 0 the inequality sign must face towards the 0

The inequality sign also must be a < or > not a ≤ or ≥ as no positive number times -11 will equal 0

so the answer would be x < 0

Answer:

Base = 18 inches

Height = 54 inches

Step-by-step explanation:

The height of a parallelogram is three times its base. If the area is 972 square inches, what is the base and height?

The area of a parallelogram is given as:

Base × Height

Height = h = 3b

Area = 972 square inches

We substitute

972 = b × 3b

972 = 3b²

Divide both sides by 3.

b² = 972/3

b² = 324

b = √324

b = 18 inches

Solving for h

h = 3b

h = 3 × 18

h = 54 inches

Therefore,

Base = 18 inches

Height = 54 inches

The number of cards sold for Mother's Day by Owen is 16.

Total cards=800

Percentage of sold cards =2%

A percentage is a value per hundred.

So, 2% of 800 = (2*800)/100

2% of 800 =1600/100

2% of 800 =16

So, owen sold 16 cards

Hence, the number of cards sold by Owen is 16.

Answer:

The simplified ratio is 7:6

Step-by-step explanation:

First we have to find the GCF of both 154 and 132.  Since the GCF is 22, we will divide 154 by 22 and we get 7.  Now divide 132 by 22 and we get 6.  Therefore, the simplest form or the ratio 154:132 is 7:6.

Answer:

Step-by-step explanation:

Total members in the choir = 24 + 36 = 60

a) Percentage of men = [tex]\frac{24}{60}*100[/tex]

                                 = 4 * 10  = 40%

b) Percentage of women = 60%

c) Number of men =24 + 10 = 34 men

Number of women = 36 + 10 = 46

Total = 34 + 46 = 80

Percentage of men = [tex]\frac{34}{80}*100= 42.5[/tex]%

Percentage of women = (100 - 42.5)% = 57.5%

Answer:

% of men = 24/60 × 100

% of men = 4/10 × 100

% of men = 4 × 10

% of men = 40%

b]

% of women = 36/60 × 100

% of women = 6/10 × 100

% of women = 6 × 10

% of women = 60%
