Answer:

(1, 0) ; (3, 0)

Step-by-step explanation:

Answer:

144

Step-by-step explanation:

Answer:

54

Step-by-step explanation:

This is a right angle (complementary angles) so 90-43 is 47 and the angel is x - 7 so you have to add 7. Answer is 54 <3

Answer:

[tex] x = (-1)\ \& \ y =1[/tex]

Step-by-step explanation:

Given :-

And we need to find out the ordered pair is the solution of the system . The system is ,

[tex]\begin{cases} x + 3y = 2 \quad \dots (i) \\\\ 2y - x =3\quad \dots (ii) \end{cases}[/tex]

We can see that the signs of x are opposite in the given equation .So on adding we can eliminate x .

On adding the equations :-

[tex]\implies 3y + 2y = 3+2 \\\\\implies 5y = 5 \\\\\implies y = 1 [/tex]

Substitute for y :-

[tex]\implies 3 + x = 2 \\\\\implies x = 2-3 \\\\\implies x = -1 [/tex]

Hence the value of x is -1 and y is 1

Answer:

t = 4

Step-by-step explanation:

In step two, instead of multiplying by -6 on both sides, you need to divide by -6 to isolate t.

-6t = -24

÷-6    ÷-6

t = 4

When you multiply by -6 on both sides, the equation would be 36t = 144, which is not what we want. The opposite of multiplication is division, and in order to get the answer, you divide by the number multiplied.

Step-by-step explanation:

Answer:

20 inches

Step-by-step explanation:

Step 1: Subtract the total from what was left

[tex]95 - 15 = 80[/tex]

Step 2: Divide the result into the 4 pieces

[tex]80 \div 4[/tex]

[tex]=\frac{80}{4}[/tex]

[tex]= 20[/tex]

Each of the four pieces Lily cut was 20 inches.

Answer:

(0, 1/3, 2/3, 1, 1 1/3, 1 2/3, 2)

Step-by-step explanation:

Given :. Length of row = yards

Spacing = 1/3 yard

Startibg point = 0

0 ;

0+1/3 = 1/3

1/3 + 1/3 = 2/3

2/3 + 1/3 = 2/3 = 1

1 + 1/3 = 1 1/3

1 1/3 + 1/3 = 1 2/3

1 2/3 + 1/3

(0, 1/3, 2/3, 1, 1 1/3, 1 2/3, 2)

Answer:

[tex]h(x) = -4(x - 2)(x + 2)[/tex]

Step-by-step explanation:

Given

[tex]h(x) = -4(x - 2)(x + 2)[/tex]

[tex]h(x) = -2(2x^2 - 8)[/tex]

[tex]h(x) = -4(x^2 - 4)[/tex]

[tex]h(x) = -4x^2 + 16[/tex]

Required

Which shows the zeros of h(x)

To determine the zeros of a function, the function must be written as:

[tex]h(x) = n(x \± a)(x \± b)[/tex]

Where

[tex]n \ne 0[/tex]

[tex]\± a,\± b[/tex] are the zeros

Of options (a) to (d), only (a) is written in the form:

[tex]h(x) = n(x \± a)(x \± b)[/tex]

i.e.

[tex]h(x) = -4(x - 2)(x + 2)[/tex]

Other options do not show the zeros

12x

This is the answer.

Because 3×4x = 12x

Answer:

3 students with red hair

12 students with brown hair

Step-by-step explanation:

1/6 times 18 = 18/6 = 3 students with red hair

4/6 times 18 = (18 times 4)/6= 12 students with brown hair

Answer:

Red=3

Brown=12

Step-by-step explanation:

So to find 1/6 of 18 you divide 18 by 6 which is 3.

red = 3

Then to find 4/6 well you've already found out 1/6 is 3 so all you need to do is times that by 4.

3x4=12

Brown = 12

Answer:

A.

Step-by-step explanation:

Ed's answer is correct but I would have just multiplied each side by the reciprocal of 2/3 which is 3/2, which will isolate 'm'

m = 1/4 x 3/2

m = 3/8

Answer:

They need to make at least 12 batches.

Step-by-step explanation:

First, we need to find how many cookies in total, so we multiply 70 by 4.

70*4 = 280.

Secondly, 1 batch makes 2 dozen cookies, or technically 24 cookies. So we need to find how many batched with 280 divided by 24. This results in 11.6 repeating. But if you round it up, you get 12.

Time to check:

12 * 24 = 288. So it's the amount of cookies needed with 8 remaining.

Hope this helps.
