{y+7=3x6x−2y=12



The only solution is (14, 12) .


The only solution is (12, 14) .


There is no solution.


There are an infinite number of solutions.

Answers

Answer 1

Answer:

there is no solution

Step-by-step explanation:

y + 7 = 3x

6x - 2y = 6    which can be simplied to be 3x - y = 6  (divide by 2)

let y = 3x - 7

substitute:  3x -(3x - 7) = 6

                  3x - 3x + 7 = 6

                              7 ≠ 6  therefore, no solution

Find WZY. (helpp fast)

Answers

Answer:

[tex]m\angle WZY = 24^\circ[/tex]

Step-by-step explanation:

Angles and Lines

The figure shows two triangles WXZ and WYZ. Considering:

* Angles WXZ and WYZ are right (90°)

* Sides XW and YW are congruent (red marker on both)

* They share the side WZ.

We can conclude they are congruent. Thus, angles XZW and YZW are congruent or have the same measure:

5x + 4 = 6x

Subtracting 5x:

4 = x

Or, x =4

Thus:

[tex]m\angle WZY = 6x = 24^\circ[/tex]

[tex]\mathbf{m\angle WZY = 24^\circ}[/tex]

Answer:

[tex]2x(4x+3)[/tex]

Step-by-step explanation:

The first thing to factorising this expression is to find the greatest common factor (GCF). For 8x² and 6x the gcf is 2x. So now we divide the 8x² and 6x by the 2x. Which comes out to 4x and 3, these will be inside the parentheses.

So it'll factorise to [tex]2x(4x+3)[/tex] and remember when we are dividing with exponents we subtract the exponents. So [tex]\frac{8x^2}{2x}[/tex] we will divide the coefficients together that'll be 4 and now for the exponents the 2 on the x² minus the 1 on the x will equal 1 so it'll be just x we don't place a one or anything.

Tyler has a baseball bat that weighs 28 ounces. Find this weight in kilograms and in grams. Explain or show your reasoning. (Note: 1 kilogram 35 ounces)

Answers

Answer:

Weight in Kilograms = 0.8 Kilograms

Weight in grams = 800 grams

Step-by-step explanation:

Tyler has a baseball bat that weighs 28 ounces.

a) Weight in Kilograms

From the question:

1 kilogram = 35 ounces

Hence:

35 ounces = 1 kilogram

28 ounces = x kilogram

Cross Multiply

35 × x = 28 × 1

x = 28/35

x = 0.8 kilograms

b) Weight in grams

1 kilogram = 1000 grams

0.8 kilogram = x

Cross Multiply

x = 0.8 × 1000 grams

x = 800 grams

Chad has a bag with 2 mint sticks, 11 jelly treats, and 7 fruit tart chews. If he eats one piece every 4 minutes, what is the probability his first two pieces will be a jelly treat and a mint stick and represent as a percent to the nearest tenth if necessary?

Answers

Answer:

first you add all the candies together to get 20 in the bag

2+11+7=20

jelly treat:

now we divide 11 by 20 to get a decimal

11/20= .55

multiply .55 by 100 to change it to a percentage

.55*100=55

first part of answer: He has a 55% chance of getting a jelly treat

mint stick:

divide 2 by 20 to get a decimal

2/20=.1

change .1 to a percent by multiplying by 100

.1*100=10

second part of answer: he has a 10% chance of getting a mint stick
