For the first one, it should be 5x=50-30 which 5x=20 and x=4 so she needs to read 4 books
For the second one, it should be
(50-(7*5)/5)*7 or (50-35/5)*7= 5*7=35
Sorry if I'm wrong!

NISA [10]

The rigid transformations that maps ΔABC onto ΔFED by reflection then translation.

The correct option is (B).

<h3>What is Translation?</h3>

Translation is also another form of transformation whereby all the points of a figure are shifted at exactly the same distance and in the same direction without being resized, reflected nor rotated.

given:

ΔABC ≅ ΔFED are congruent by the SSS Congruence Theorem.

Hence, the rigid transformations that maps ΔABC onto ΔFED by reflection then translation.

Bao is mixing flour and water to make dough. The graph shows how much water he uses for different amounts of flour.
Butoxors [25]

Answer:

0.33 liters of water Bao use per liter of flour.

3  liters of flour Bao use per liter of water

Step-by-step explanation:

Given the graph which pass through the coordinates (0,0) and (3,1)

∴ Equation of line passing through these points can be written as

(y-y')=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}(x-x')

⇒  (y-0)=\frac{1-0}{3-0} (x-0)

⇒ y=\frac{1}{3}x ⇒ 3y=x

Now, we have to find liters of water Bao use per liter of flour i.e if x=1 then we find the value of y which is 3y=x=1 ⇒ y=\frac{1}{3} = 0.33 l

Now, we have to find  liters of flour Bao use per liter of water i.e if y=1 the we have to find the value of x which is x=3 litre

What does a quadratic equation look like?
sergeinik [125]

Answer:

a{x}^{2} + bx + c = 0

Step-by-step explanation:

A quadratic equation is an equation of the second degree, meaning it contains at least one term that is squared. The standard form is ax² + bx + c = 0 with a, b, and c being constants, or numerical coefficients, and x is an unknown variable. One absolute rule is that the first constant "a" cannot be a zero.

<h3>Examples of quadratic equations include all of these:</h3>

y =  {x}^{2} + 3x + 1
