Answer:
substitute the given values for m, n, and p into each problem and solve. Make sure you don't ignore minuses and negatives. Separate with parentheses to make sure you don't get confused.
Step-by-step explanation:
54: -7(-5) - 10( 3/2)
35 - 10(1.5)
35 - 15
20
55. -3mnp
-3 x (-5) x 3/2 x (-8)
15 x 1.5 x (-8)
22.5 x (-8)
-180
56. 8n / (-6p)
8(1.5) / (-6 x -8)
12 / 48
1/4 or .25
57. p squared is (-8)(-8)
2(-8)(-8)(-1.5) / (-5)
128 (-1.5) / (-5)
-192/ (-5) negatives cancel out
192/5
38.4

Answer:
your answer is 70
Step-by-step explanation:
Hello there!
Given the sequence:
The question reveals it to be geometric sequence since it has common ratio.
<u>G</u><u>e</u><u>o</u><u>m</u><u>e</u><u>t</u><u>r</u><u>i</u><u>c</u><u> </u><u>S</u><u>e</u><u>q</u><u>u</u><u>e</u><u>n</u><u>c</u><u>e</u> / <u>R</u><u>a</u><u>t</u><u>i</u><u>o</u><u> </u><u>F</u><u>o</u><u>r</u><u>m</u><u>u</u><u>l</u><u>a</u>
<u></u>
Define 'r' as common ratio.
First, let's check the common ratio by using the formula above.
<u>R</u><u>a</u><u>t</u><u>i</u><u>o</u><u> </u><u>C</u><u>h</u><u>e</u><u>c</u><u>k</u>
Therefore, the common ratio or r-value is -3.
To find the 7th term of sequence, you can by using the General Geometric Terms.
<u>G</u><u>e</u><u>n</u><u>e</u><u>r</u><u>a</u><u>l</u><u> </u><u>T</u><u>e</u><u>r</u><u>m</u><u> </u><u>o</u><u>f</u><u> </u><u>G</u><u>e</u><u>o</u><u>m</u><u>e</u><u>t</u><u>r</u><u>i</u><u>c</u>
a1 is defined as the first term of sequence.
r is common ratio.
n is the term.
Since we want to find 7th term:
Therefore, the 7th term of this sequence is 729.
