Answer: A) x + 4x = 35; 7 large stones and 28 small stones
======================================================
Explanation:
x = number of large stones
4x = number of small stones
x+4x = total number of stones = 35
x+4x = 35 is the equation to solve
-----------
Let's isolate x
x+4x = 35
5x = 35
x = 35/5
x = 7 large stones are needed
4x = 4*7 = 28 small stones are needed
Answer:
The correct option is;
D. 6,5
Step-by-step explanation:
TS and TU are midsegments
Segment PR = 18.2
Segment TS = 6.5
Given that TS is the midsegment of PR and PQ, therefore, TS = 1/2×QR
Which gives;
Segment QR = 2×TS = 2 × 6.5 = 13
Segment QR = 13
Given that TU is a midsegment to PQ and QR, we have that QU = UR
Segment QR = QU + UR (segment addition postulate)
Therefore, QR = QU + QU (substitute property of equality)
Which gives;
QR = 2×QU
13 = 2×QU
Segment QU = 13/2 = 6.5
The length of segment QU is 6.5.
Answer:
L = 56, W = 40
Step-by-step explanation:
192 = 14x + 10x
x = 8
length = 8*7 = 56
width = 5*8 = 40
The repeating decimal .99999 is equal to 1.
This can be proven by doing the following math
Answer:
One num = 6x = 6 x 70 = 420
Second= 4x = 4 x 70 = 280
Step-by-step explanation:
6x + 4x = 700
10x = 700
x = 700/10 = 70
One num = 6x = 6 x 70 = 420
Second= 4x = 4 x 70 = 280
I hope im right!
