Answer:
x=5
Step-by-step explanation:
∠D=∠E (angles opposite to equal sides are equal)
So, 
=3x+10
10=-3x
10=x(x-3)
we know 5×2= 10 & 5-3=2,
So, 10=5×(5-3)
10=5×2
∴x=5
Answer: Write the problem as a mathematical expression x= in2 over 4
Step-by-step explanation:
Answer:
Step-by-step explanation:
Looking at the given graph, the slope of the line is expressed as
Slope = (y2 - y1)/(x2 - x1)
y2 = 19.5
y1 = 9.5
x2 = 6
x1 = 1
Slope = (19.5 - 9.5)/(6-1)
Slope = 10/5 = 2
The successive terms is increasing by 2
The formula for the nth term of an arithmetic sequence is expressed as
Tn = a + (n - 1)d
Where
a is the first term of the sequence
n is the number of terms in the sequence.
d is the common difference.
From the information given,
a = 9.5
Tn = an
d = 2
The explicit rule for the arithmetic sequence will be
an = 9.5 + 2(n-1)
1.a)add
B) substract
C) multiply
D) one
2) 1002=1.002×10^3
3)2.8×10^-3 < 2.5×10^-2 < 1.2×103 <4×103
