For this case we have a relationship of the form:

There are 70 children on the field trip
Therefore, we must replace the value of c = 70 in the equation.
We have then:

Clearing t, we have:
Answer:
there are 15 teachers on the trip
Step-by-step explanation:
2x + 3y = 6
3y = -2x + 6
divide through by 3
y = (-2/3)x + 6............1
but equation of a straight line is
y = mx + c..............2
compare equation 1&2, m = -2/3 and c = 6
where m = gradient
c = intercept
Answer:
Step-by-step explanation:
<u>Factorize both numbers:</u>
- 900 = 2*2*3*3*5*5
- 270 = 2*3*3*3*5
<u>Common factors are:</u>
<u>So HCF is:</u>
- HCF(900, 270) = 2*3*3*5 = 90
4x+ 3 = 3(2x-5) ;x=2; x^{2} = 4
