Answer:

Step-by-step explanation:

Making x the subject of the formula;

y=x+z/a-x

Cross multiply

y(a-x) = x+z

ya - yx = x+z

Collect like terms

x+yx = ya - z

x(1+y) = ya - z

x = ya-z/1+y

Hence the value of x is ya-z/1+y

Use the following diagram for questions 4 - 6.

jonny [76]

Answer:

1. C

2. B

3. B

Step-by-step explanation:

Vertical angles are the angles opposite each other when two lines cross, thus angles with measures (x+77)° and 126° are vertical angles.

Vertical angles are congruent.

Hence,

$x+77=126\\ \\x=126-77\\ \\x=49^{\circ}$

Solve each system of equations 3x + 2y = 26 3x - 2y = 10 Ordered pair

MrMuchimi

Let's solve the following system of equations

$\begin{gathered} 3x+2y=26 \\ 3x-2y=10 \end{gathered}$

Eq 1 + Eq 2

$3x+2y+3x-2y=26+10$ $6x=36$ $x=6$

Now for y

$y=\frac{26-3x}{2}$ $y=\frac{26-3\cdot6}{2}$ $y=\frac{8}{2}$ $y=4$

Anna opens two savings accounts at the beginning of the year. She deposits $5,000 in an account that earns 2% interest each year

xenn [34]

As we know she wont be depositing or withdrawing that means that the total money remaining in the bank would be static and would just add up the interest their is.

SO 2 per cent of 5000 is 100 $. So she will earn a 100 $ from her first account.

And 2.5 % from 10000 is around 250 $ so she earn a total of 250 $ from her second account.

Now adding up the complete money that she will earn at the end of the year would be around 350 $.
