Answer:

89 more boys than girls

Step-by-step explanation:

801 * 4/9 = 356

So 356 boys

rest are girls so 801-356 = 445 girls

445-356 = 89

89 more boys than girls (there are more boys but question says there are more girls?)

I really need help with this problem...."Arliss has two pieces of carpet runner. One is 2 1/3 yards long and the other is 3 1/3

KIM [24]

2 (1/3) + 3 (1/3) is easy to add
2 + 3 = 5
(1/3) + (1/3) = (2/3)
So, it equals 5 (2/3)
She needs 10 - 5 (2/3) more
= 4 (1/3)

Find the sum of the zeros in the following equation: (2x-1)(x+8)(2x-4)(x-1)

lara [203]

Answer:

$-9\frac{1}{2}$

Step-by-step explanation:

$2x+1=0$

$2x=-1$

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

$x+8=0$

$x=-8$

$2x-4=0$

$2x=4$

$x=2$

$x-1=0$

$x=1$

$1+2-8-\frac{1}{2}$

$=-1-8\frac{1}{2}$

$=-9\frac{1}{2}$

Sum of fractions $=-9\frac{1}{2}$

Step 3: 2x > 10 Step 4: x > 5 What property justifies the work between step 3 and step 4? A. division property of inequali

BigorU [14]

Answer:

A. Division property of inequality.

Step-by-step explanation:

Let be $2\cdot x > 10$ , we proceed to show the appropriate procedure to step 4:

1) $2\cdot x >10$ Given

2) $x > 5$ Compatibility with multiplication/Existence of multiplicative inverse/Associative property/Modulative property/Result. (Division property of inequality)

In consequence, the division property of inequality which states that:

$\forall\, a, b, c \in \mathbb{R}$ . If $c > 0$ , then:

$a> b\,\longrightarrow a\cdot c > b\cdot c \,\lor\, a$

But if $c < 0$ , then:

$a> b\,\longrightarrow a\cdot c < b\cdot c \,\lor\, a b\cdot c$

Hence, correct answer is A.
