Answer: The blue team scored 12 goals.

Step-by-step explanation:

Given : The red team scored 4 goals.

The blue team scored 3 times as many goals.

Then using MULTIPLICATION OPERATION, number of goals have done by the blue team score is given by :-

$3\times4=12$

Hence, the blue team scored 12 goals.

How many Solutions does this system have? (1 point)

mixas84 [53]

The given system of equation that is $2x+y=3$ and $6x=9-3y$ has infinite number of solutions.

Option -C.

<u>Solution:</u>

Need to determine number of solution given system of equation has.

$\begin{array}{l}{2 x+y=3} \\\\ {6 x=9-3 y}\end{array}$

Let us first bring the equation in standard form for comparison

$\begin{array}{l}{2 x+y-3=0} \\\\ {6 x+3 y-9=0}\end{array}$

$\frac{a_{1}}{a_{2}}=\frac{b_{1}}{b_{2}} \neq \frac{c_{1}}{c_{2}}$

To check how many solutions are there for system of equations $a_{1} x+b_{1} y+c_{1}=0 \text{ and }a_{2} x+b_{2} y+c_{2}=0$ , we need to compare ratios of $\frac{a_{1}}{a_{2}}, \frac{b_{1}}{b_{2}} \text { and } \frac{c_{1}}{c_{2}}$

In our case,

$a_{1} = 2, b_{1}= 1\text{ and }c_{1}= -3$

$a_{2} = 6, b_{2} = 3,\text{ and }c_{2} = -9$

$\begin{array}{l}{\Rightarrow \frac{a_{1}}{a_{2}}=\frac{2}{6}=\frac{1}{3}} \\\\ {\Rightarrow \frac{b_{1}}{b_{2}}=\frac{1}{3}} \\\\ {\Rightarrow \frac{c_{1}}{c_{2}}=\frac{-3}{-9}=\frac{1}{3}} \\\\ {\Rightarrow \frac{a_{1}}{a_{2}}=\frac{b_{1}}{b_{2}}=\frac{c_{1}}{c_{2}}=\frac{1}{3}}\end{array}$

As $\frac{a_{1}}{a_{2}}=\frac{b_{1}}{b_{2}}=\frac{c_{1}}{c_{2}}$ , so given system of equations have infinite number of solutions.

Hence, we can conclude that system has infinite number of solutions.

This baseball season, Barry gets two hits for every 16 at bats. This statement represents his batting average.

Katen [24]

Answer:

A. 1/8 or 0.125

B. No

Step-by-step explanation:

A. The batting average formula is: (# of hits) ÷ (# of at-bats).

Here, we see that Barry has 2 hits and 16 at-bats, so plug these numbers into the formula:

(# of hits) ÷ (# of at-bats)

2 ÷ 16 = 1/8 = 0.125

B. Batting average is always rounded to the thousandths place; in other words, we only calculate the number up to the third decimal place.

Looking at our batting average calculated in part A, it's 0.125, which is already at the third decimal place, and we can see that there is clearly no 0 at the end. So, the answer is no.

Yumi and Juan pick up litter along the highway at the same rate. Yumi picks up litter for 3 miles and takes two hours longer tha

oksano4ka [1.4K]

Juan's time = x
Yumi's time = x + 2
Yumi's distance = 3 miles
Juan's distance = 2 miles
Rate = distance/time
Juan's rate = 2/x
Yumi's rate = 3/(x + 2)
The rates are equal so:
2/x = 3/(x + 2)
2x + 4 = 3x
x = 4 hours
Yumi's time = 4 + 2 = 6 hours
The answer is D.

Answer:

slope of n =⅔

Step-by-step explanation:

The product of the slope of two perpendicular lines(m1•m2) must equal -1.

This means that if you have the slope of one line,find it's negative reciprocal to obtain the slope of the other.

Thus,-1/(-3/2)=⅔
