Numbers are 4 and 8
<u>Step-by-step explanation:</u>
Step 1:
Let the numbers be x and y. Given that their sum is 12 and difference is 4. Form equations for this data.
⇒ x + y = 12 ------ (1)
⇒ x - y = 4 -------- (2)
Subtract eq (2) from (1)
⇒ 2x = 8
⇒ x = 4
Step 2:
Find y.
⇒ y = 12 - x = 12 - 4 = 8
Answer:
17
Step-by-step explanation:
4 × 5 - 3² x 2 ÷ 6
20 - 3² × 2 ÷ 6
20 - 9 × 2 ÷ 6
20 - 18 ÷ 6
20 - 3 = 17

Answer:
her hourly pay is £8.50
Step-by-step explanation:
h= hourly pay
n = number of hours worked over 40 hours in a week
week pay = 40h + (n x 2 x h)
544 = 40h + 2nh
52 - 40 = 12, so n = 12
544 = 40h + 2 x 12 x h
544 = 40h + 24h
544 = 64h
544/64 = 8.5 h=8.5 (£8.50)
just to check:
£8.50 x 40 = £340
£8.50 x 2 x 12 = 204
340 + 204 = 544 yayy the answer is correct
hope this helps x
plzzz can i hv brainliest
This is the slope intercept form y=mx+b and this is the standard form ax+by=c, now I am going to show you how to do this with numbers so is much easier. Say we have 4x+2y=10 as a standard form we have to set y by itself first we have to subtract 4x from both sides (because in order to get rid of a positive you have to use a negative) now we have 2y=-4x+10, now our next step is to divide both sides by 2 to leave y by itself (because in order to get rid of a multiplication is with a division) this gives you y=-4/2x+10/2. now our final step is to simplify what we can in this case 4 can be divide by 2 and get 2 and 10 can be divide by 2 and get 5 this means our simplified form is y=-2x+5
Hope this helps
