X= 29 because it is a right angle, and all right angles are = to 90, so you subtract 61 from 90.
Y= 29
Z= 61

Answer:

See Explanation

Step-by-step explanation:

Your question is incomplete, as the equations or graph or table(s) were not given.

However, I'll give a general way of solving this.

Take for instance, the equations are:

$y = \frac{4}{3}x - 1$

$y = \frac{2}{3}x - \frac{1}{2}$

To do this, we start by equating both equations.

$y = y$

i.e.

$\frac{4}{3}x - 1= \frac{2}{3}x - \frac{1}{2}$

Collect Like Terms

$\frac{4}{3}x - \frac{2}{3}x= 1 - \frac{1}{2}$

Take LCM

$\frac{4x- 2x}{3}= \frac{2 - 1}{2}$

$\frac{2x}{3}= \frac{1}{2}$

Cross Multiply

$2x * 2 = 3 * 1$

$4x = 3$

Make x the subject

$x = \frac{3}{4}$

Substitute 3/4 for x in $y = \frac{4}{3}x - 1$

$y = \frac{4}{3} * \frac{3}{4} - 1$

$y = 1 - 1$

$y = 0$

Hence:

$(x,y) = (\frac{3}{4},0)$

If 2 cups of ketchup= 1 cup of tomato sauce, then ____ cups of ketchup= 2.25 cups of tomato sauce.

SashulF [63]

We have an equation: 2/1= ?/2.25

Cross multiply:
1*?= 2*2.25
⇒ ?= 2*2.25= 4.5

The final answer is 4.5~

Answer:

$53750

Step-by-step explanation:

Sam deposit $12500 every year which grows at a simple interest of 3% and we have to calculate the total sum after 4 years.

If Sam deposit $x with r% simple interest then the principal will grow after 4 years to $x[1 + \frac{4r}{100}]$

Again, for the second year $x investment with r% simple interest will grow to $x[1 + \frac{3r}{100}]$ .

Now, the third year $x investment with r% simple interest will grow to $x[1 + \frac{2r}{100}]$

And finally the fourth year $x investment with r% simple interest will grow to $x[1 + \frac{r}{100}]$

Therefore, the total sum becomes

$x[1 + \frac{4r}{100}] + x[1 + \frac{3r}{100}] + x[1 + \frac{2r}{100}] + x[1 + \frac{r}{100}]$

= $4x + \frac{10 \times r \times x}{100}$

= $4x + \frac{rx}{10}$

So, in case of Sam the sum will be = $4 \times 12500 + \frac{3 \times 12500}{10}$ = $53750
