Answer:

Therefore, B) 2.5 + (-1.5) = 1.0 is true.

Step-by-step explanation:

Given : Number sentences .

To find : Which number sentence is true.

Solution : We have given that numbers

We need to prove that is true,

Condition for true statement , left hand side and right hand side must be equal.

Then , 2.5 + (-1.5) = 1.0

Removing parenthesis

2.5 - 1.5 = 1.0

1.0 = 1.0

Left hand side is equal to right hand side.

Therefore, B) 2.5 + (-1.5) = 1.0 is true.

Juan and Franco collect baseball cards. Juan has baseball cards. Franco has 18 fewer baseball cards than Juan. Together they hav

horsena [70]

Answer:

Franco has 66 baseball cards.

Step-by-step explanation:

This question can be solved by a system of equations.

I am going to say that:

x is the number of baseball cards that Franco has.

y is the number of baseball cards that Juan has.

Franco has 18 fewer baseball cards than Juan.

This means that:

$x = y - 18$

Also:

$y = x + 18$

Together they have 150 baseball cards.

This means that:

$x + y = 150$

Since $y = x + 18$

$x + x + 18 = 150$

$2x = 132$

$x = \frac{132}{2}$

$x = 66$

Franco has 66 baseball cards.

The contrapositive of p q is:

Kay [80]

Some symbols are missing. I'm assuming you meant to put in a horseshoe symbol like so $p \supset q$

If so, then the contrapositive of that would be $\sim q \supset \ \sim p$ which is the final answer.

The tilde sign $\sim$ means "not" so writing $\sim q$ means "not q" which is the complete opposite of q.

Please help me and others that will stumble on this problem.

lutik1710 [3]

Answer:

A (0,0)

Step-by-step explanation:

When a function intersects the y-axis then the point of intersection is called y-intercept of the function,

Also, for y-intercept x = 0.

That is, if f(x) is the function then its y-intercept is (0, f(0) )

By the given table for x = 0, f(x) = 0

Hence, the y-intercept of the given function is (0,0),

Option A is correct.

Find three consecutive odd integers whose sum is 13 more than twice the largest of the three intergers

Yuki888 [10]

15,17,19
Suppose the three odd integers are #n#, #n+2# and #n+4#
Their sum is:
#n + (n+2) + (n+4) = 3n+6#
#13# more than twice the largest of the three is:
#2(n+4)+13 = 2n+21#
From what we are told these two are equal:
#3n+6 = 2n+21#
Subtract #2n+6# from both sides to get:
#n = 15#
So the three integers are:
#15, 17, 19#
