Answer:
Thomas has 45
Emma 30+45=75 pound
Step-by-step explanation:
Ratio is 3/5
Tomas receives x money
Emma receives x+30
3/5=x/30+x
3(30+x)=5x
90+3x=5x
90=5x-3x
90=2x
x=90/2=45
Thomas has 45
Emma 30+45=75 pound
45/75=3/5
Answer:
y = 3x + 12
Step-by-step explanation:
y = 3x - 5 (y = 3x +b)
Parallel lines have same slope.
m = 3; (-2 , 6)
y - y1 = m(x -x1)
y - 6 = 3(x -[-2])
y -6 = 3(x + 2)
y - 6 = 3x + 6
y = 3x + 6 + 6
y = 3x + 12
Jessica’s mistake is that when isolating h from b, she multiplied b instead of dividing it on both sides. The new formula for h would be A/2b=h.
Now let’s solve. 23/2(6)=h
23/12
Approx. 1.91
Answer:
169 sq cm
Step-by-step explanation:
Bread rolls = BR
Ketchup = K
Sausages = S
2BR +1K + 3S = £10 - 45p
2BR + 1K + 3S = £9.55
2BR = 1.40 x 2 = £2.80
1K = £1.80
£2.80 + £1.80 + 3S = £9.55
3S = £9.55 - £2.80 - £1.80
3S = £4.95
£4.95 / 3 = BR
S = £1.65
The answer is £1.65 for one pack of sausages
