Answer:

0.4

Step-by-step explanation:

-1/5 = -2/10 = -0.2, -1/4 = -25/100 = -0.25

-0.25-(-1/5)+0.2+(-1/4) = -0.25+0.2+0.2+0.25 = -0.25+0.25+0.2+0.2 = 0.4

Identify the reflection of the figure with vertices P(−11,−13), Q(−17,19), and R(23,−27) across the x-axis.

Bess [88]

Answer:

P (−11, 13), Q (−17, −19), R (23, 27)

Step-by-step explanation:

we know that

The reflection of a figure across the x-axis has the following rule

(x,y) -----> (x,-y)

P(-11,-13) -----> P(-11,13)

Q(-17,19) -----> Q(-17,-19)

R(23,-27) ----> R(23,27)

Answer with explanation please

Rasek [7]

Answer:

x = 8

Step-by-step explanation:

-4 + 8x = 6x + 12

Subtract 6x from both sides

-4 + 2x = 12

URGENT!! A student needs 3 pieces of wire for a science project. The second piece must be 3 times as long as the first. The thir

Marianna [84]

Answer:

Part a) The inequality that represent the situation is

$x+(3x)+(6x) \leq 350\ in$

Part b) The possible lengths of the shortest piece of wire are all positive real numbers less than or equal to $35\ inches$

Step-by-step explanation:

Let

x------> the length of the first wire

3x---> the length of the second wire

2(3x)=6x -----> the length of the third wire

Part a) WRITE AN *INEQUALITY* THAT MODELS THE SITUATION

we know that

The inequality that represent the situation is

$x+(3x)+(6x) \leq 350$

Part b) WHAT ARE THE POSSIBLE LENGTHS OF THE SHORTEST PIECE OF WIRE?

we know that

The shortest piece of wire is the first wire

Solve the inequality

$x+(3x)+(6x) \leq 350$

$10x \leq 350$

$x \leq 35\ in$

The possible lengths of the shortest piece of wire are all positive real numbers less than or equal to $35\ inches$
