Answer:Recognise three numbers that are related through the operations of addition and subtraction.
Recognise that there are two related addition and two subtraction equations in a 'family of facts'.
Write and read sets of related addition and subtraction equations.
Step-by-step explanation:that is all
We are working with completing ratios.
So we have the initial ratio 1:40.
We need to solve 6:x
What we do to one side of a ratio, we have to do to the other so it is even.
We multiplied the blueprint by 6, so we need to multiply the other side.
6×40
240
So, the actual length is 240 in (not sure if that is the unit of measurement since it is not listed).
Yes 2/5 and 4/10 are equivalent fractions. This is because you are able to multiple both numbers in 2/5 by 2 and get 4/10. In addition, you can divide both numbers in 4/10 by 2, therefore they’re equivalent.
Answer:
128cm²
Step-by-step explanation:
<em>To find out how much material he needs, you need to find the surface area of the box. Each box has 6 sides, 2 of 3 different sides. </em>
Surface area = 2(6 × 4) + 2(6 × 4) + 2(4 × 4)
= 128cm²
<u>Answer</u>
Center: (1,-12)
Radius: 5

-2x+24y+120=0 (Subtract 120 on both sides and rearrange)
-2x++24y=-120 (Then divide 2 by 2 and square it. Do the same for 24.)
-2x+1++24y+144=-120+1+144 (You have to add the same numbers on both sides)
(Simplify)
So you would put (1,-12); r=5
