Answer:
£30
Step-by-step explanation:
Gavyn has £18 more than Alex
—› G - A = £18
—› 4u - 1u = 3u = £18
1u = £18 ÷ 3
= £6
total units = 4 + 1 = 5
5u = 5 × £6 = £30

The expression for total marbles is given as: T = 4 m + 3</h3>
Step-by-step explanation:
Here, the question is <u>incomplete</u>.
Helena lost her marbles. But then she found them and put them in 4 bags with m marbles in each bag. She had 3 marbles left over that didn't fit in the bags. How many marbles does Helena have in all? Write your answer as an expression.
The total number of bags filled with marbles = 4
The number of marbles in each bag = m
So, total number of marbles in 4 bags = 4 x ( Marbles in 1 bag)
= 4 x (m) = 4 m
The left number of marbles = 3
So, the total marbles = (total marbles in 4 bag) + left out marbles
or, T = 4 m + 3
Hence, the expression for total marbles is given as: T = 4 m + 3
First you would simplify the equation <span>(7x²+2x+5)+(3x²-8x-10) lets start with the first part
</span><span>(7x²+2x+5)
</span>7x² + 2x which = 49x + 2x which also = 51x Then you add the last part (+5)
51x + 5
Now you simplify the last part.
<span>(3x²-8x-10)
</span>3x²-8x which=9x - 8x which also = 1x or simply x Then add the last part (-10) Which you'll get x-10
51x + 5) + (x - 10) = 52x -5
so your answer is 52x - 5
