$\frac{16}{7}$ Answer:

X = -16/7

Step-by-step explanation:

Multiply the numbers

4 x 2 + 8 = -7x

8 + 8 = -7x

Add the numbers

8 + 8 = -7x

16= -7x

Divide both sides by the same factor

16= -7x

16 divided bu -7x and -7x divided by -7x

Simplify

-16 divided by 7 not negative 7 and -7 divided by -7

Cancel terms that are in both the numerator and denominator

cancel out -7 divided by -7 and you get -16/7 left

so, therefore x= -16/7

Rectangle A measures 12 cm by 3 cm. Rectangle B is a scaled copy of Rectangle A. Select all of the measurement pairs that could

Lana71 [14]

Answer:

A, D, and E

Step-by-step explanation:

The ratio between the sides of the rectangle is 12/3 = 4. In a scaled copy of rectangle A, the ratio between the sides needs to be 4 too.

For answer A the 6/1.5 = 4, has the same ratio therefore is a scaled version of rectangle A

For answer B the 10/2 = 5, it does not has the same ratio therefore is not a scaled version of rectangle A

For answer C the 13/4 = 3.25, it does not has the same ratio therefore is not a scaled version of rectangle A

For answer D the 18/4.5 = 4, has the same ratio therefore is a scaled version of rectangle A

For answer E the 80/20 = 4, has the same ratio therefore is a scaled version of rectangle A

MVUT =175, mVUJ=17x-3, and mJUT=17x+8. Find x

kotykmax [81]

The diagram of the three angles is shown below with point U as the point where all three lines meet.

Angles property: Angles around a point add up to 360°

We set up an equation

$175+17x-3+17x+8=360$
$180+34x=360$
$34x=360-180$
$34x=180$
$x= \frac{180}{34}= \frac{90}{17}$

A group of 72 children completed a survey on what kind of sport they like. The choices were: Chess, Swimming, and Football. Ever

hichkok12 [17]

Answer:

$\dfrac{17}{72}$

Step-by-step explanation:

From the given information:

Total number of students, $n(U)=72$

The choices were: Chess(C), Swimming(S), and Football(F).

Everyone liked at least one sport except 7 kids, $n( C \cup F \cup S)'=7$

Chess is not an active sport; and

10 children liked Chess only, $n( C \cap F' \cap S')=10$

The probability that a randomly-chosen child from this group does not like active kinds of sport is the Probability that a student plays chess only or like no kind of sport at all.

$P( C \cup F \cup S)'+P(C \cap F' \cap S')=\dfrac{n( C \cup F \cup S)'+n(C \cap F' \cap S')}{n(U)} \\=\dfrac{10+7}{72} \\=\dfrac{17}{72}$
