Answer:

The ordered pair will simply be the point at which these two lines cross. We solve the equations as simultaneous equations.

The solution is the point

(

−

,

−

11

)

Explanation:

We solve the set of two equations as simultaneous equations.

Call this Equation 1:

y

=

2

x

+

Call this Equation 2:

y

=

x

−

Rearrange Equation 2 to make

x

the subject:

x

=

y

+

5

Substitute this value of

x

into Equation 1:

y

=

Answer:

B

Angle on a straight line is 180 degrees. Angle ABC is 90. You're given angle FBE as 47. So, it is 180-(90+47)= 43. That's the angle ABF.

Answer:

You need to increase the amount of pizza sold by 24%, you can do it one of two ways:

236*0.24 = 56.64 and then do 236 + 56.64 = 292.64

(this way you find out what 24% of 236 is and then add it to 236 to get an increase of 24% )

or you can do this:

236 *1.24 = 292.64

(this way you're finding out what 124% of 236 is. I find this way easier because there's less steps. it works because you're still finding out what 24% is, you're just keeping the 236 there)

either way they need to sell 293 pizza's to get the prize

Answer:

-8

Step-by-step explanation:

As we know, slope is rise over run. We count up and over until we get to the next dot. To get to the next dot, we count 8 up and -1 over (since we go to the left, not the right). We can put this in a fraction (rise/run). That gets us 8/-1, which can be simplified to -8.

Answer:

  20.9 inches

Step-by-step explanation:

The perimeter length is the sum of the lengths of the two straight edges and that of the curved edge.

  P = r + r + rα . . . . . where α is the central angle in radians

35° is (35°/180°)π radians, about 0.6109 radians

Then the perimeter is ...

 P = r(2 +α) = (8 in)(2 +0.6109) ≈ 20.9 in

The perimeter of the slice is about 20.9 inches.

Answer:

A

Step-by-step explanation:

Z is the same as the answer to the equation so if you add 18 and 96 together you will get z

also sum means adding

Answer: a

Step-by-step explanation:

the answer has addition and it says 18+96=z so i believe that theyre trying to say that whatever you add is gonna equal z so i believe the correct answer is a (:

Step-by-step explanation:

Difference of squares: A² - B² = (A + B)(A - B).

Therefore 49x² - 16 = (7x)² - (4)² = (7x + 4)(7x - 4).

The correct answer is Option B.

Answer:

No solution.

Step-by-step explanation:

The given equations are :

x−3y=6 ...(1)

x−3y=−3 ...(2)

We need to solve the above equations.

The above two lines are parallel. Forparallel lines,

[tex]\dfrac{a_1}{a_2}=\dfrac{b_1}{b_2}\ne \dfrac{c_1}{c_2}[/tex]

Here,

[tex]\dfrac{a_1}{a_2}=\dfrac{b_1}{b_2}[/tex]

It means, the above equations have no solution.

Answer:

She can buy 0 to 11.75 pounds of tomatoes.

Step-by-step explanation:

Consider the provided information.

It is given that Susan can spend no more than $30 on ingredients. She buys all ingredients except for tomatoes for $6.50. Tomatoes cost $2 per pound.

It means she can only spend less than or equal to $30. Let x be the pounds of tomatoes she can buy.

So, the required inequality should be:

[tex]30\leq 6.50+2x[/tex]

Now simplify the inequality.

[tex]30-6.50\leq 2x[/tex]

[tex]23.5 \leq 2x[/tex]

[tex]11.75\leq x[/tex]

Hence, she can buy 0 to 11.75 pounds of tomatoes.

Step-by-step explanation:

0.6 hours = 2.5 miles

=> 1 hour = 2.5 miles * (1/0.6) = 4.16 miles.

Hence Noan runs 4.16 miles in 1 hour.

(or 25/6 miles)

Answer: See the attached image below

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

Explanation:

The problem doesn't state this, but I'm assuming we have the same amount of each type of card. For instance, we could have 10 of each card.

The probability of getting any one type is 1/5 = 0.2 since there's one type we're after out of 5 shapes total. If we had 10 of each card, then the probability of getting a diamond is 10/50 = 1/5 = 0.2; note how there are 5*10 = 50 cards total.

If we expect 50 diamonds, then this must mean that 50/0.2 = 250 trials were conducted. You have the correct answer for the first box.

If we do 200 trials, then we expect (1/5)*200 = 40 cards would be a pentagon card. That explains row 2.

If we do 150 trials, then we expect (1/5)*150 = 30 star cards. The value 30 goes in the second box.

The value 300 goes in the third box. We find this by computing 60/0.2, or we can multiply 5 by 60. Note how (1/5)*300 = 60.

Lastly, if we conduct 50 trials, then we expect 10 circle cards because (1/5)*50 = 10.

Side note: the values 100 and 20 are not used.

Answer:

y=0/0

Step-by-step explanation:

Step 1: Add -y to both sides.

y+z+−y=y+z+−y

z=z

Step 2: Add -z to both sides.

z+−z=z+−z

0=0

Step 3: Divide both sides by 0.

0/0=0/0

y=0/0

Step-by-step explanation:

Answer:

2.7 < x 12.3

Step-by-step explanation:

using triangle inequality theorem:

(3 scenarios, discount the one that produce a negative)

4.8 + 7.5 > x        x < 12.3

4.8 + x > 7.5        x > 2.7

7.5 + x > 4.8    (discount)

Answer:

add the ratio parts together

5 + 2 = 7

divide the total number of students by the total number of parts

35/7 = 5

now multiply each part of the ratio by 5

girls 10

there are 25 boys

Answer:

-16x+14.8

Step-by-step explanation:
