Andre draws a tape diagram for 3÷2/3
bija089 [108]

Answer:

No I do not agree with Andre says that 3 divided by 2/3 Solving for 3 ÷ 2/3

3 ÷ 2/3

= 3 × 3/2

= 9/2

= 4 1/2

Therefore, 3 divided by 2/3 is 4 1/2

Andre's reasoning is wrong.

Step-by-step explanation:

It is incorrect

Let's divide and compare the sum

3 : 2/3 = 3*3/2 = 9/2 = 4 1/2

and

There are four 2/3 fractions and one 1/3 fraction

The 1/3 fraction is 1/2 of 2/3 fraction so instead of counting 1/3 as 1/3 it should be counted as 1/2

How do you solve: 4/10y+28=0
Bezzdna [24]

Answer:

<h2>y = -70</h2>

Step-by-step explanation:

\dfrac{4}{10}y+28=0\qquad\text{subtract 28 from both sides}\\\\\dfrac{4:2}{10:2}y=-28\\\\\dfrac{2}{5}y=-28\qquad\text{multiply both sides by 5}\\\\5\!\!\!\!\diagup^1\cdot\dfrac{2}{5\!\!\!\!\diagup_1}y=-140\\\\2y=-140\qquad\text{divide both sides by 2}\\\\y=-70

The points in the table lie on a line. Find the slope of the line.
Wewaii [24]

Answer:

Slope (m) = -\frac{3}{4}

Step-by-step explanation:

Using any two pairs from the table of values given, (-2, 5) and (2, 2):

Slope (m) = \frac{y_2 - y_1}{x_2 - x_1}

Where,

(-2, 5) = (x_1, y_1)

(2, 2) = (x_2, y_2)

Plug in the value into the slope formula:

Slope (m) = \frac{2 - 5}{2 -(-2)}

Slope (m) = -\frac{3}{4}
