X // Y, Y // Z,
By inference X // Z
The third option.
So cost=(# of items) times (Price per item)
necklace=48 bbeads and 1 charm
1 bead=0.05
charm=0.45
so we multiply
necklace=48(0.05)+1(0.45)
necklace=2.4+0.45
necklace=2.85
bracelet=25 beads and 4 charms
bracelet=25(0.05)+4(0.45)
bracelet=1.25+1.8
bracelet=3.05
necklace=$2.85
bracelet=$3.05
There are 8 tens in the number 1,384.
Each digit in the number has an equivalent value based on its placement in the number.
1,384 where:
1 is in the thousands value
3 is in the hundreds value
8 is in the tens value
4 is in the ones value
The extended form of 1,384 is:
1 x 1000 + 3 x 100 + 8 x 10 + 4 x 1 = 1,384
1,000 + 300 + 80 + 4 = 1,384
8 x 10 = 80 ; shows that there are 8 10s in the number with a product of 80.
Answer:
Step-by-step explanation:
those are 2 lines, and to graph them find 2 points for each to draw a line trough them
line 1
y-2x=0 so y=2x
pick any value for x
(x=1, y=2*1=2), (x=3, y=2*3=6)
Draw a line trough points (1,2) and (3,6)
line 2
y=4x+3
(x=1, y=4*1+3=7), (x= -1, y= 4(-1)+3= -1)
Draw a line trough points (1,7) and (-1, -1)
I will do number 1 only. You can then use my solution steps to do the rest.
Solve 4x + 5 > 5x − 2 for x.
4x + 5 > 5x − 2
4x - 5x > - 2 - 5
-x > -7
Dividing both sides by a negative number reverses the inequality sign. In other words, the sign > becomes < in the reply.
-x/-1 < -7/-1
x < 7
Answer: x < 7
The answer here means that whatever the value of x is for question 1, it must be less than 7.
You finish.
